* \section introduction Introduction
*
* \cite{nfft3} Fast Fourier transforms (FFTs) belong \cite{nfft3_2} to the '10 algorithms with the
* greatest influence on the development and practice of science and
* engineering \cite{nfft3} in the 20th century'.
* The classic algorithm computes the discrete Fourier transform
* \f[
* f_j= \sum_{k=-\frac{N}{2}}^{\frac{N}{2}-1} \hat{f}_{k}
* {\rm e}^{2\pi{\rm i}\frac{kj}{N}}
* \f]
* for \f$j=-\frac{N}{2},\hdots,\frac{N}{2}-1\f$ and given complex
* coefficients \f$\hat{f}_{k}\in\mathbb{C}\f$.
* Using a divide and conquer approach, the number of floating point
* operations is reduced from \f${\cal O}(N^2)\f$ for a straightforward
* computation to only \f${\cal O}(N\log N)\f$.
* In conjunction with publicly available efficient implementations the fast
* Fourier transform has become of great importance in scientific computing.
* However, two shortcomings of traditional schemes are the need for
* equispaced sampling and the restriction to the system of complex
* exponential functions.
* The NFFT is a C subroutine library for computing the nonequispaced discrete
* Fourier transform (NDFT) and its generalisations in one or more dimensions,
* of arbitrary input size, and of complex data.
*
* More precisely,we collect the possible frequencies
* \f$\mathbf{k}\in\mathbb{Z}^d\f$ in the multi-index set
* \f[
* I_{\mathbf{N}} := \left\{ \mathbf{k}=\left(k_t\right)_{t=0,\hdots,d-1}
* \in \mathbb{Z}^d: -
* \frac{N_t}{2} \le k_t < \frac{N_t}{2} ,\;t=0,\hdots,d-1\right\},
* \f]
* where \f$\mathbf{N}=\left(N_t\right)_{t=0,\hdots,d-1}\f$ is the
* multibandlimit, i.e., \f$N_t\in 2\mathbb{N}\f$.
* For a finite number of given Fourier coefficients
* \f$\hat f_{\mathbf{k}} \in \mathbb{C}\f$,
* \f$\mathbf{k}\in I_{\mathbf{N}}\f$, we consider the
* fast evaluation of the trigonometric polynomial
* \f[
* f\left(\mathbf{x}\right)
* := \sum_{ \mathbf{k}\in I_{ N}} \hat{f}_{\mathbf{ k}}
* {\rm e}^{-2\pi{\rm i}\mathbf{k}\mathbf{ x}}
* \f]
* at given nonequispaced nodes \f$\mathbf{x}_j \in \mathbb{T}^d\f$,
* \f$j=0,\ldots, M-1\f$, from the
* \f$ d\f$-dimensional torus as well as the
* adjoint problem, the fast evaluation of sums of the form
* \f[
* \hat h_{\mathbf{k}} := \sum_{j=0}^{M-1} {f}_{j}
* {\rm e}^{2\pi{\rm i}\mathbf{k}\mathbf{ x}_j}.
* \f]
*
* \subsection generalisations Generalisations
*
* The generalisations of the NFFT include
* - NNFFT - nonequispaced in time and frequency fast Fourier transform,
* - NFCT/NFST - nonequispaced fast (co)sine transform,
* - NSFFT - nonequispaced sparse fast Fourier transform,
* - FPT - fast polynomial transform,
* - NFSFT - nonequispaced fast spherical Fourier transform.
*
* Furthermore, we consider the inversion of the above transforms by
* iterative methods.
*
* \section faq FAQ - Frequently Asked Questions
*
*
* - Can NFFT be built on Windows?
*
* Since version 3.2, NFFT should build on Windows systems under MinGW.
* It might be necessary to add the --disable-shared option to
* configure to silence linker warnings.
*
* Building under Cygwin does not work since NFFT relies on data types
* and functions declared in complex.h. While some of them are
* available as built-in functions in gcc, not all needed by NFFT are
* provided.
*
* Building NFFT with other compilers, e.g. Microsoft's Visual C++, has
* no been tested. If you have successfully be able to build NFFT, you
* can send us all relevant information and we will share it with
* others on our website.

List of files and purpose
README this file
simple_test.c introductory example how to use the nfft
flags.c compares different precomputation strategies for the nfft
flags.m visualisation with MATLAB, loads data files
'flags.data0.gaussian', ... (previously computed by the
executable flags (where the window function has to be set
and the whole library needs recompilation); calls also the
executable taylor_nfft
ndft_fast.c compares different precomputation strategies for the ndft
ndft_fast.m visualisation with MATLAB, calls the executable ndft_fast
nfft_benchomp.c runs benchmarks for nfft OpenMP code and writes results as
pgfplots to nfft_benchomp_results_plots.tex, uses
nfft_benchomp_createdataset.c and nfft_benchomp_detail.c
nfft_times.c compares 1d, 2d, and 3d times to compute nffts and ffts,
outputs a latex-table
taylor_nfft.c compares the nfft with a taylor expansion based one
taylor_nfft.m visualisation with MATLAB, calls the executable taylor_nfft

RM is the name of the program to use to delete files associated with each FILE
(typically \`/bin/rm'). RM-OPTIONS are options (such as \`-f') to be passed
to RM.
If FILE is a libtool library, object or program, all the files associated

Compile a source file into a libtool library object.
This mode accepts the following additional options:
-o OUTPUT-FILE set the output file name to OUTPUT-FILE
-no-suppress do not suppress compiler output for multiple passes
-prefer-pic try to build PIC objects only
-prefer-non-pic try to build non-PIC objects only
-shared do not build a \`.o' file suitable for static linking
-static only build a \`.o' file suitable for static linking
-Wc,FLAG pass FLAG directly to the compiler
COMPILE-COMMAND is a command to be used in creating a \`standard' object file
from the given SOURCEFILE.
The output file name is determined by removing the directory component from
SOURCEFILE, then substituting the C source code suffix \`.c' with the
library object suffix, \`.lo'."

Automatically set library path, then run a program.
This mode accepts the following additional options:
-dlopen FILE add the directory containing FILE to the library path
This mode sets the library path environment variable according to \`-dlopen'
flags.
If any of the ARGS are libtool executable wrappers, then they are translated
into their corresponding uninstalled binary, and any of their required library
directories are added to the library path.
Then, COMMAND is executed, with ARGS as arguments."

Link object files or libraries together to form another library, or to
create an executable program.
LINK-COMMAND is a command using the C compiler that you would use to create
a program from several object files.
The following components of LINK-COMMAND are treated specially:
-all-static do not do any dynamic linking at all
-avoid-version do not add a version suffix if possible
-bindir BINDIR specify path to binaries directory (for systems where
libraries must be found in the PATH setting at runtime)
-dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime
-dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols
-export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
-export-symbols SYMFILE
try to export only the symbols listed in SYMFILE
-export-symbols-regex REGEX
try to export only the symbols matching REGEX
-LLIBDIR search LIBDIR for required installed libraries
-lNAME OUTPUT-FILE requires the installed library libNAME
-module build a library that can dlopened
-no-fast-install disable the fast-install mode
-no-install link a not-installable executable
-no-undefined declare that a library does not refer to external symbols
-o OUTPUT-FILE create OUTPUT-FILE from the specified objects
-objectlist FILE Use a list of object files found in FILE to specify objects
-precious-files-regex REGEX
don't remove output files matching REGEX
-release RELEASE specify package release information
-rpath LIBDIR the created library will eventually be installed in LIBDIR
-R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries
-shared only do dynamic linking of libtool libraries
-shrext SUFFIX override the standard shared library file extension
-static do not do any dynamic linking of uninstalled libtool libraries
-static-libtool-libs
do not do any dynamic linking of libtool libraries
-version-info CURRENT[:REVISION[:AGE]]
specify library version info [each variable defaults to 0]
-weak LIBNAME declare that the target provides the LIBNAME interface
-Wc,FLAG
-Xcompiler FLAG pass linker-specific FLAG directly to the compiler
-Wl,FLAG
-Xlinker FLAG pass linker-specific FLAG directly to the linker
-XCClinker FLAG pass link-specific FLAG to the compiler driver (CC)
All other options (arguments beginning with \`-') are ignored.
Every other argument is treated as a filename. Files ending in \`.la' are
treated as uninstalled libtool libraries, other files are standard or library
object files.
If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
only library objects (\`.lo' files) may be specified, and \`-rpath' is
required, except when creating a convenience library.
If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
using \`ar' and \`ranlib', or on Windows using \`lib'.
If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file
is created, otherwise an executable program is created."

Instead it simply concatenates the arguments, separated by ' ', and calls
CreateProcess(). We must quote the arguments since Win32 CreateProcess()
interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a
special way:
- Space and tab are interpreted as delimiters. They are not treated as
delimiters if they are surrounded by double quotes: "...".
- Unescaped double quotes are removed from the input. Their only effect is
that within double quotes, space and tab are treated like normal

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the "deleted header file" problem.

## dummy dependencies for each header file. Too bad gcc doesn't do

nfft-3.2.3/ChangeLog 0000644 0000710 0000337 00000010057 12137737447 011164 0000000 0000000 This file contains the version history for NFFT 3.x.x.
Changes in version 3.2.3
- Added a workaround for an internal compiler error occuring with gcc 4.7.1
in kernel/mri
- Added a workaround for a compilation error in the MATLAB mex interface for
gcc 4.7.1 when compiling with C99 support (-std=gnu99)
Changes in version 3.2.2:
- Fixed several problems introduced in version 3.2.1
- Fixed an issue when the configure script would not run correctly when using
the option --with-fftw3.
Changes in version 3.2.1:
- Added missing files of new nfft MATLAB (class) interface to release.
Changes in version 3.2.0:
- Added support for OpenMP. To activate, use the configure script with the
--enable-openmp option.
- Added ticks.h from FFTW to leverage CPU cycle counters. If cycle counters
are available, the configure script will try to determine the number of
ticks per second. If successful, example programs measure times in seconds.
Otherwise, example programs will output raw cycle counter differences in
arbitrary units. If cycle counters are not available, results of time
measurements are undefined.
- Renamed functions of direct (non-fast) algorithms to
_direct, e.g. the function name for the
direct computation of the non-equispaced Fourier transform is
nfft_trafo_direct(nfft_plan) instead of ndft_trafo(nfft_plan).
Changes in version 3.1.4:
- Added pkg-config file (thanks Gert Wollny)
- Headers include/nfft3util.h, applications/fastsum/fastsum.h, and
applications/fastsum/kernels.h can now be included by C++ compilers.
- Fixed an error that occured when trying to create symbolic links to Matlab mex
files during installation.
- All programs from the application and examples subdirectories are no longer
installed. The same holds for the Matlab code from the matlab subdirectory.
Changes in version 3.1.3:
- Fixed some issues that can cause C++ compilers to fail. Thanks to Romain Bossart.
- Fixed an error that caused linking against FFTW while checking compiler
characteristics in the configure script. This only affected installations where
FFTW had been installed in a custom location.
- Doxygen generated documentation is now only deleted if the target
maintainer-clean is used. The documentation is no longer deleted if the user
invokes the usual clean target.
Changes in version 3.1.2:
- Fixed a bug in fpt_precompute() that caused excessive stabilization and
incorrect results.
- Fixed three bugs in the nfft: window function defines are moved to the
internal header infft.h, a larger lookup table is used for PRE_LIN_PSI, and
nfft_adjoint for d=2,3 and PRE_FULL_PSI writes its output correctly.
Changes in version 3.1.1:
- Added a workaround for an internal compiler error occuring with gcc 4.3.2.
Changes in version 3.1.0:
- The FPT example program, that is, examples/fpt/simple_test has been
modified to not require the NFCT module anymore. This solves the problem
that NFFT won't compile when the FPT module has been switched on while the
NFCT module is swithced off.
Changes in version 3.1.0:
- A module, called nfsoft, for fast Fourier transforms on the rotation group
SO(3) has been added.
- It is now possible to configure the build process so that only specific
modules are compiled and installed. Invoke the configure script with option
"--help" for details.
- The handling of how to link against the fftw3 library has been improved. The
new configure script options "--with-fftw3", "--with-fftw-includedir", and
"--with-fftw-libdir" allow to specify where fftw3 has been installed.
- Improved compliance with GNU standards.
- The experimental Matlab interface has been improved and is now officially a
part of NFFT3. To compile the Matlab modules, invoke the configure script
with the option --with-matlab=. Also, an interface
to the plain NFFT has been added.
Changes in version 3.0.2:
- Fixed a bug in the fpt module that lead to wrong output.

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
Copyright (C)
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

dnl
dnl On Pentium and later x86 processors, with gcc or a compiler that
dnl has a compatible syntax for inline assembly instructions, run
dnl a small program that executes the cpuid instruction with
dnl input OP. This can be used to detect the CPU type.
dnl
dnl On output, the values of the eax, ebx, ecx, and edx registers
dnl are stored as hexadecimal strings as "eax:ebx:ecx:edx" in
dnl the cache variable ax_cv_gcc_x86_cpuid_OP.
dnl
dnl If the cpuid instruction fails (because you are running a cross-compiler,
dnl or because you are not using gcc, or because you are on a processor
dnl that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP is set
dnl to the string "unknown".
dnl
dnl This macro mainly exists to be used in AX_GCC_ARCHFLAG.

# SYNOPSIS
#
# AX_OPENMP([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro tries to find out how to compile programs that use OpenMP a
# standard API and set of compiler directives for parallel programming
# (see http://www-unix.mcs/)
#
# On success, it sets the OPENMP_CFLAGS/OPENMP_CXXFLAGS/OPENMP_F77FLAGS
# output variable to the flag (e.g. -omp) used both to compile *and* link
# OpenMP programs in the current language.
#
# NOTE: You are assumed to not only compile your program with these flags,
# but also link it with them as well.
#
# If you want to compile everything with OpenMP, you should set:
#
# CFLAGS="$CFLAGS $OPENMP_CFLAGS"
# #OR# CXXFLAGS="$CXXFLAGS $OPENMP_CXXFLAGS"
# #OR# FFLAGS="$FFLAGS $OPENMP_FFLAGS"
#
# (depending on the selected language).
#
# The user can override the default choice by setting the corresponding
# environment variable (e.g. OPENMP_CFLAGS).
#
# ACTION-IF-FOUND is a list of shell commands to run if an OpenMP flag is
# found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
# not found. If ACTION-IF-FOUND is not specified, the default action will
# define HAVE_OPENMP.

# serial 5 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

dnl @summary find target architecture name for gcc -march/-mtune flags
dnl @category Misc
dnl
dnl This macro tries to guess the "native" arch corresponding to
dnl the target architecture for use with gcc's -march=arch or -mtune=arch
dnl flags. If found, the cache variable $ax_cv_gcc_archflag is set to this
dnl flag and ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is
dnl is set to "unknown" and ACTION-FAILURE is executed. The default
dnl ACTION-SUCCESS is to add $ax_cv_gcc_archflag to the end of $CFLAGS.
dnl
dnl PORTABLE? should be either [yes] (default) or [no]. In the former case,
dnl the flag is set to -mtune (or equivalent) so that the architecture
dnl is only used for tuning, but the instruction set used is still
dnl portable. In the latter case, the flag is set to -march (or equivalent)
dnl so that architecture-specific instructions are enabled.
dnl
dnl The user can specify --with-gcc-arch= in order to override
dnl the macro's choice of architecture, or --without-gcc-arch to
dnl disable this.
dnl
dnl When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
dnl called unless the user specified --with-gcc-arch manually.
dnl
dnl Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
dnl
dnl (The main emphasis here is on recent CPUs, on the principle that
dnl doing high-performance computing on old hardware is uncommon.)

dnl floating-point computations can be re-ordered as needed.

Answer to the Referee Report\\[2ex]
{\Large
``Using NFFT 3 -- a software library for various \\ nonequispaced fast
Fourier transforms'' }\\[2ex]
by Jens Keiner, Stefan Kunis, and Daniel Potts
\end{center}
%===============================================================================
First of all, we thank all three referees for their helpful comments and valuable
suggestions.
\section*{Referee 3}
\label{sect:1}
\begin{itemize}
\item
\begin{quote}
Referee:
The authors may consider to follow or mention the other commonly
recognized names, such as USFFT by many mathematicians
and NUFFT by engineers.
\end{quote}
%We now mention the alternative abbreviations USFFT and NUFFT on the first
%Ppage of the paper.
References and the alternative abbreviations USFFT and NUFFT are contained
in the Appendix ``Further NFFT approaches'' (now A.4).
\item
\begin{quote}
Referee:
This package does not take arbitrary sample nodes as it claims.
The samples are required to be on a Kronecker grid, which
may be non-equally spaced in each and every dimension involved.
\end{quote}
The software library \emph{does} take arbitrary sample nodes. We do not
require samples to be on a Kronecker grid or anything similar.
\item
\begin{quote}
Referee:
The package limits the data structure to linearized arrays,
which entails additional code and time for data re-formatting
for high-dimensional NUFFTs.
\end{quote}
Data structures are linear and we do not see this as a
substantial limitation. Like FFTW, we expect multi-dimensional data to be
stored as a consecutive block in row-major order ('C order').
Fixed-size arrays allocated by the user are amenable to convenient multiple
applications of the \verb"[]" operator, e.g. \verb"a[2][4][1]", but the use
of such arrays cannot recommended in general (e.g., they are allocated on
the stack). For dynamic arrays, the linear index has to be computed.
Additionally, for nonequispaced transforms, nodes can be
completely unstructured and multi-dimensional structures, like grids,
are special cases. Most often, nodes will not be aligned
and the most appropriate data structure for such nodes is, without further
assumptions, a linear array.
A current limitation is that (for now) we do not support strided
data (i.e., general FFTW-style i/o tensors) or vectors of transforms.
\item
\begin{quote}
Referee:
The algorithm description in Section 2.2 is unacceptable. It mentions the
arithmetic complexity only.
\end{quote}
Memory requirements strongly depend on the precomputation technique
employed. NFFT 3 offers different strategies here ranging from no
precomputation at all (everything evaluated on-line) to
full precomputation (can be expensive in terms of memory). In
Section 2.4 (which was 2.2), we now include a forward reference to
Appendix 2.3 where details are given.
\item
\begin{quote}
Referee:
It fails to specify the essential algorithm components. It
uses the standard FFT, which is preceded by a numerical
re-sampling step with arithmetic complexity proportional linearly
to the data size.
\end{quote}
The last paragraph of Section 2.4 (was 2.2) now briefly mentions
the essential components of the NFFT algorithm. For details, we still refer the
reader to Appendix A.2.
\item
\begin{quote}
Referee:
Unlike the FFT, the complexity grows fast with the dimensionality.
\end{quote}
A $d$-dimensional FFT of degree $N$ (in each dimension) has a complexity of
$\mathcal{O}(N^{d} \log N)$.
A $d$-dimensional NFFT of degree $N$ (in each dimension) with $M$ nodes has
a complexity of $\mathcal{O}(N^{d} \log N + |\log\varepsilon|^d M)$. Both
algorithms grow exponentially with the number of dimensions $d$. But it is
true that for the NFFT, also the constant $|\log\varepsilon|^d$ in front
of the number of nodes $M$ grows exponentially which does not happen in
the FFT.
\item
\begin{quote}
Referee:
In addition, an algorithm shall be described with companion
data structures and the features of algorithm parameters.
Specifically, the re-sampling factor shall be singled out at least
and explained.
\end{quote}
The last paragraph of Section 2.4 (was 2.2) now mentions the oversampling
factor and the truncation parameter. For details, we still refer the reader to
Appendix A.3. The chief aim of this article is to describe the math behind the NFFT
routines implemented in the NFFT 3 library, as well as basic usage principles
and applications. We do not think it would serve the purpose of
the paper to give details of the implementation and technical concerns.
\item
\begin{quote}
Referee:
There are many typos and grammar errors. (Need a professional
proof-reader to help out.)
\end{quote}
We have done our best to fix the mistakes.
\item
\begin{quote}
Referee:
Performance metrics and comparison objectives shall be clearly
noted.
\end{quote}
As mentioned, our aim is not to describe all details of the implementation.
But we now summarise performance related tests in Section 5. The focus is
to observe how the NFFT algorithm does behave in comparison to the
FFT and to the direct evaluation NDFT.
It is nevertheless true that more extensive numerical tests at a
mature state of the library are desirable. At the current stage, an
extensive and in-depth performance analysis is not available.
\item
\begin{quote}
Referee:
This manuscript uses more space on examples and applications.
It will serve the purpose of the paper if the examples and applications
are used to demonstrate the range of functions and their
parameters and the scope of performance tuning the library supports.
The complexity in terms of arithmetic operations explains
only why the fast algorithms are implemented, but does not say
how well they are implemented in this particular software library.
\end{quote}
Clearly, the numerical results support the theoretical complexity
and error estimates.
New columns in Table 5.2 have been added to show that the NFFT
is only a reasonable factor slower than the FFT.
Moreover, our library is open source (i.e., improvements are very welcome)
and it is to the best of our knowledge the only available implementation
(besides various \textsc{MatLab}-implementations).
\item
\begin{quote}
Referee:
There are two fundamental assumptions/limitations (a) the sample
locations for higher-dimensional FFTs on unequispaced be on
a Kronecker grid and (b) the sample data be in linearized and
consecutively packed data arrays.
\end{quote}
See comments above.
\item
\begin{quote}
Referee:
No README file or other documentation is found in the third
party code directory.
\end{quote}
Had been added in the meantime.
\item
\begin{quote}
Referee:
No explicit mention of using the third party code FFTW, although
it is mentioned in the installation section.
\end{quote}
We now mention the internal use FFTW in Sections 1 (first paragraph) and
2.4 (last paragraph).
\item
\begin{quote}
Referee:
The input and output data structures for high-dimensional transforms
are not clear, especially, on each particular type of grids,
such Cartesian grid or spherical grid.
\end{quote}
The referee is right in that details of input and output data
structures for generalisations of the NFFT (NFSFT, NNFFT,...)
are not given explicitly. Details are found in the API
documentation acompanying the downloadable software package.
We do not think that it would improve the paper to mention
the same here.

\section{Introduction}\label{sect:1}
\setcounter{equation}{0}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
This tutorial surveys the fast Fourier transform at nonequispaced nodes (NFFT),
its generalisations, its inversion, and the related C library NFFT \nfftversion.
The goal of this manuscript is twofold -- to shed some light on the
mathematical background, as well as to provide an overview over the C library
to allow the user to use it effectively. Following this, this document splits
into two parts:
In Sections \ref{sect:nfft}, \ref{sect:gen} and \ref{sect:inv}, we
introduce the NFFT which, as a starting point, leads to several concepts for
further generalisation and inversion. We focus on a mathematical
description of the related algorithms. However, we complement the necessarily
incomplete quick glance at the ideas by references to related mathematical
literature.
In Section \ref{sect:nfft}, we introduce the problem of computing the discrete
Fourier transform at nonequispaced nodes (NDFT), along with the notation
used and related works in the literature. The algorithms (NFFT) are developed
in pseudo code.
Furthermore, we turn for recent generalisations, including in particular NFFTs
on the sphere and iterative schemes for inversion of the nonequispaced FFTs,
in Section \ref{sect:gen} and \ref{sect:inv}, respectively.
Having laid the theoretical foundations, Section \ref{sect:lib} provides an
overview over the NFFT \nfftversion\ C library and the general principles for using the
available algorithms in your own code. Rather than describing the library
interface in every detail, we restrict to simple recipes in order to
familiarise with the very general concepts sufficient for most everyday tasks.
For the experienced user, we provide full interface documentation
(see \verb+doc/html/index.html+ in the package directory) which gives
detailed information on more advanced options and parameter settings for
each routine. Figure \ref{nfft:fig:svn} gives an overview over the directory
structure of the NFFT \nfftversion\ package.
Finally, Section \ref{sect:ex} gives some simple examples for using the
library and some more advanced applications are given in Section
\ref{sec:appl}
along with numerical results.

\end{figure}
%The computational complexity of the proposed algorithms is $\cO(|I_{\mathbf{N}}|
%\log |I_{\mathbf{N}}| + M)$ for $|I_{\mathbf{N}}|$ equispaced frequencies and $M$
%nonequispaced samples.
%Besides the core module for the nonequispaced FFT, the following tree
%structure shows various generalisations, a module for inverse transforms, some
%examples, and recent applications.
%The remainder of this tutorial is organised as follows:
%The implementation and usage of the library is described in Section
%\ref{sect:library}.

\section{Notation, the NDFT, and the NFFT}\label{sect:nfft}
\setcounter{equation}{0}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
This section summarises the mathematical theory and ideas behind the NFFT.
Let the torus
\begin{equation*}
\T^d
:= \left\{ \mathbf{x}=\left(x_t\right)_{t=0,\hdots,d-1} \in \R^d: - \frac{1}{2}
\le x_t < \frac{1}{2},\; t=0,\hdots,d-1 \right\}
\end{equation*}
of dimension $d\in\N$ be given.
It will serve as domain from which the nonequispaced nodes $\mathbf{x}$ are taken.
Thus, the sampling set is given by ${\cal X}:=\{\mathbf{x}_j \in
\T^d:\,j=0,\hdots,M-1\}$.
Possible frequencies $\mathbf{k}\in\Z^d$ are collected in the multi-index set
\begin{equation*}
I_{\mathbf{N}} := \left\{ \mathbf{k}=\left(k_t\right)_{t=0,\hdots,d-1} \in \Z^d: -
\frac{N_t}{2} \le k_t < \frac{N_t}{2} ,\;t=0,\hdots,d-1\right\},
\end{equation*}
where $\mathbf{N}=\left(N_t\right)_{t=0,\hdots,d-1}$ is the {\bf EVEN}
multibandlimit, i.e., $N_t\in 2\N$.
To keep notation simple, the multi-index $\mathbf{k}$ addresses elements of
vectors and matrices as well, i.e., the plain index $\tilde
k:=\sum_{t=0}^{d-1} (k_t+\frac{N_t}{2}) \prod_{t'=t+1}^{d-1} N_{t'}$
is not used here.
The inner product between the frequency index $\mathbf{k}$ and the time/spatial
node $\mathbf{x}$ is defined in the usual way by $\mathbf{k} \mathbf{x}:=k_0 x_0 + k_1 x_1
+\hdots+ k_{d-1} x_{d-1}$.
Furthermore, two vectors may be combined by the component-wise product $\mathbf{\sigma}
\odot \mathbf{N}:=\left(\sigma_0 N_0, \sigma_1 N_1, \hdots, \sigma_{d-1} N_{d-1},
\right)^{\top}$ with its inverse $\mathbf{N}^{-1}:=\left(\frac{1}{N_0},
\frac{1}{N_1}, \hdots, \frac{1}{N_{d-1}} \right)^{\top}$.
The space of all $d$-variate, one-periodic functions $f: \T^d \rightarrow \C$
is restricted to the space of $d$-variate trigonometric polynomials
\begin{equation*}
T_{\mathbf{N}}:={\rm span}\left(\eim{\mathbf{k}\mathbf{\cdot}}:\,\mathbf{k} \in I_{\mathbf{N}}\right)
\end{equation*}
with degree $N_t\; (t=0,\hdots,d-1)$ in the $t$-th dimension.
The dimension $\dim T_{N}$ of the space of $d$-variate trigonometric
polynomials $T_{N}$ is given by $\dim T_{N} = |I_{\mathbf{N}}| =
\prod\limits_{t=0}^{d-1} N_t$.
%------------------------------------------------------------------------------
\subsection{NDFT - nonequispaced discrete Fourier transform}
%------------------------------------------------------------------------------
The first problem to be addressed can be regarded as a matrix vector
multiplication. For a finite number of given Fourier coefficients
$\hat f_{\mathbf{k}} \in \C$, $\mathbf{k}\in I_{\mathbf{N}}$, we consider the evaluation of the
trigonometric polynomial
\begin{equation} \label{trigPoly}
f\left(\mathbf{x}\right) := \sum_{\mathbf{k}\in I_{\mathbf{N}}} \hat{f}_{\mathbf{k}}
\eim{\mathbf{k}\mathbf{x}}
\end{equation}
at given nonequispaced nodes $\mathbf{x}_j \in \T^d$.
Thus, our concern is the evaluation of
\begin{equation}\label{eq:nfft}
f_j = f\left(\mathbf{x}_j\right) := \sum_{\mathbf{k}\in I_{\mathbf{N}}} \hat{f}_{\mathbf{k}}
\eim{\mathbf{k}\mathbf{x}_j},
\end{equation}
$j=0,\hdots,M-1$.
In matrix vector notation this reads
\begin{equation} \label{ndft}
\mathbf{f}=\mathbf{A} \mathbf{\hat{f}}
\end{equation}
where
\begin{equation*}
\mathbf{f}:=\left(f_j\right)_{j=0,\hdots,M-1},\quad
\mathbf{A}:=\left(\eim{\mathbf{k}\mathbf{x}_j}\right)_{j=0,\hdots,M-1;\;\mathbf{k}\in I_{\mathbf{N}}},
\quad
\mathbf{\hat{f}}:=\left(\hat{f}_{\mathbf{k}}\right)_{\mathbf{k}\in I_{\mathbf{N}}}.
\end{equation*}
The straightforward algorithm for computing this matrix vector product,
which is called NDFT, takes $\cO(M |I_{\mathbf{N}}|)$ arithmetical operations.
A closely related matrix vector product is the adjoint NDFT
\begin{equation*}
\mathbf{\hat{h}}=\mathbf{A}^{\adj} \mathbf{f}, \qquad \hat h_{\mathbf{k}}=\sum_{j=0}^{M-1}
\hat{f}_{ j} \eip{\mathbf{k}\mathbf{x}_j},
\end{equation*}
where $\mathbf{A}^{\adj}=\overline {\mathbf{A}}^{\top}$ denotes the conjugate transpose
of the nonequispaced Fourier matrix $\mathbf{A}$.
\subsubsection*{Equispaced nodes}
For $d\in\N,\;N_t=N\in 2\N$, $t=0,\hdots,d-1$ and $M=N^d$ equispaced nodes
$\mathbf{x}_{\mathbf{j}}={1 \over N}\mathbf{j}$, $\mathbf{j} \in I_{\mathbf{N}}$ the computation of
\eqref{ndft} is known as multivariate discrete Fourier transform (DFT).
In this special case, the input data $\hat{f}_{\mathbf{k}}$ are called discrete
Fourier coefficients and the samples $f_{\mathbf{j}}$ can be computed by the well
known fast Fourier transform (FFT) with only $\cO(|I_{\mathbf{N}}| \log |
I_{\mathbf{N}}|)$ arithmetic operations.
Furthermore, one has the inversion formula
\begin{equation*}
\mathbf{A} \mathbf{A}^{\adj}=\mathbf{A}^{\adj} \mathbf{A}= |I_{\mathbf{N}}| \mathbf{I},
\end{equation*}
which does {\bf NOT} hold true for the nonequispaced case in general.
%------------------------------------------------------------------------------
\subsection{NFFT - nonequispaced fast Fourier transform}
\label{sec.nfft}
%------------------------------------------------------------------------------
For the sake of simplicity, we explain the ideas behind the NFFT for the
one-dimensional case $d=1$ and the algorithm NFFT.
The generalisation of the FFT is an approximative algorithm and has
computational complexity ${\cal O}\left(N \log N + \log
\left(1/\varepsilon\right) M\right)$, where $\varepsilon$ denotes the
desired accuracy.
The main idea is to use standard FFTs and a window function $\varphi$ which is
well localised in the time/spatial domain $\mathbb{R}$ and in the frequency
domain $\mathbb{R}$.
Several window functions were proposed in \cite{duro93,bey95,st97,four,fesu02}.
The considered problem is the fast evaluation of
\begin{equation} \label{trigPoly1d}
f\left(x\right) = \sum_{k\in I_N} \hat{f}_k \eim{k x}
\end{equation}
at arbitrary nodes $x_j \in \T,\;j=0,\hdots,M-1$.
\subsubsection*{The ansatz}
One wants to approximate the trigonometric polynomial $f$ in
(\ref{trigPoly1d}) by a linear combination of shifted 1-periodic window
functions $\tilde \varphi$ as
\begin{equation}\label{s1}
s_1\left(x\right) := \sum_{l \in I_n} g_{l} \; \tilde \varphi\left(x -
\frac{l}{n}\right) \, .
\end{equation}
With the help of an oversampling factor $\sigma >1$, the FFT length is given by
$n:=\sigma N$.
\subsubsection*{The window function}
Starting with a reasonable window function $\varphi:\R\rightarrow\R$, one
assumes that its 1-periodic version $\tilde\varphi$, i.e.
\begin{equation*}
\tilde \varphi\left(x\right):=\sum_{r \in \Z} \varphi\left(x+r\right)
\end{equation*}
has an uniformly convergent Fourier series and is well localised in the
time/spatial domain $\T$ and in the frequency domain $\mathbb{Z}$.
The periodic window function $\tilde \varphi$ may be represented by its
Fourier series
\begin{equation*}
\tilde \varphi\left(x\right)=
\sum_{k\in \Z} c_k\left(\tilde\varphi\right) \eim{k x}
\end{equation*}
with the Fourier coefficients
\begin{equation*}
c_k\left( \tilde \varphi \right)
:=\int\limits_{\T} \tilde \varphi \left(x\right) \eip{k x} \, {\rm d} x
= \int\limits_{\mathbb{R}} \varphi \left(x\right) \eip{k x} \, {\rm d} x
= \hat \varphi \left(k\right),\quad k\in\Z.
\end{equation*}

\label{fig:window_fun}
\end{figure}
\subsubsection*{The first approximation - cut-off in frequency domain}
Switching from the definition (\ref{s1}) to the frequency domain, one obtains
\begin{equation*}
s_1\left(x\right)
=\sum_{k \in I_n} \hat g_k \, c_k\left(\tilde \varphi\right) \, \eim{k x}
+\sum_{r \in \Z \backslash \left\{0\right\}} \sum_{k \in I_n} \hat g_k \,
c_{k + n r} \left(\tilde \varphi\right) \, \eim{(k + n r)x }
\end{equation*}
with the discrete Fourier coefficients
\begin{equation} \label{coeff}
\hat g_k := \sum_{l \in I_n} g_l \, \eip{\frac{k l}{n}}.
\end{equation}
Comparing (\ref{trigPoly1d}) to (\ref{s1}) and assuming
$c_k\left(\tilde\varphi\right)$ small for $|k|\ge n-\frac{N}{2}$ suggests to
set
\begin{equation} \label{coeff2}
\hat g_k := \left\{
\begin{array}{ll}
\frac{\hat f_k}{c_k \left(\tilde \varphi\right)} & \text{for } k \in I_N
, \\[1ex]
0 & \text{for } k \in I_n \backslash I_N . \\
\end{array}
\right.
\end{equation}
Then the values $g_l$ can be obtained from (\ref{coeff}) by
\begin{equation*}
g_l = \frac{1}{n}\sum\limits_{k \in I_N} \hat g_k \, \eim{\frac{k l}{n}}
\qquad (l \in I_n),
\end{equation*}
a FFT of size $n$.
This approximation causes an aliasing error.
\subsubsection*{The second approximation - cut-off in time/spatial domain}
If $\varphi$ is well localised in time/space domain $\mathbb{R}$ it can be
approximated by a function
\begin{equation*}
\psi\left(x\right)=\varphi\left(x\right) \chi_{[-{m \over n},{m \over
n}]}\left(x\right)
\end{equation*}
with ${\rm supp} \, \psi \, \left[-{m \over n},{m \over n}\right], \;m \ll
n,\; m\in \N$.
Again, one defines its one periodic version $\tilde \psi$ with compact support
in $\T$ as
\begin{equation*}
\tilde \psi\left(x\right)=\sum_{r \in \Z} \psi\left(x+r\right).
\end{equation*}
With the help of the index set
\begin{equation*}
I_{n,m} \left(x_j\right) := \left\{ l \in I_n : n x_j - m \le l \le n x_j +
m \right\}
\end{equation*}
an approximation to $s_1$ is defined by
\begin{equation} \label{approx}
s\left(x_j\right) := \sum_{l \in I_{n,m}\left(x_j\right) } g_l \,
\tilde\psi\left(x_j - {l \over n}\right) \, .
\end{equation}
Note, that for fixed $x_j\in \T$, the above sum contains at most
$(2m+1)$ nonzero summands.
This approximation causes a truncation error.
\subsubsection*{The case $d>1$}
Starting with the original problem of evaluating the multivariate
trigonometric polynomial in (\ref{trigPoly}) one has to do a few
generalisations.
The window function is given by
\begin{equation*}
\varphi\left(\mathbf{x}\right):=\varphi_0\left(x_0\right)
\varphi_1\left(x_1\right) \hdots \varphi_{d-1}\left(x_{d-1}\right)
\end{equation*}
where $\varphi_t$ is an univariate window function.
Thus, a simple consequence is
\begin{equation*}
c_{\mathbf{k}}\left(\tilde \varphi\right)
= c_{k_0}\left(\tilde \varphi_0\right) c_{k_1}\left(\tilde \varphi_1\right)
\hdots c_{k_{d-1}}\left(\tilde \varphi_{d-1}\right).
\end{equation*}
The ansatz is generalised to
\begin{equation*}
s_1\left(\mathbf{x}\right) := \sum_{\mathbf{l} \in I_{\mathbf{n}}} g_{\mathbf{l}} \; \tilde
\varphi\left(\mathbf{x} - \mathbf{n}^{-1}\odot\mathbf{l}\right),
\end{equation*}
where the FFT size is given by $\mathbf{n}:=\mathbf{\sigma} \odot \mathbf{N}$ and the
oversampling factors by
$\mathbf{\sigma}=\left(\sigma_0,\hdots,\sigma_{d-1}\right)^{\top}$.
Along the lines of (\ref{coeff2}) one defines
\begin{equation*}
\hat g_{\mathbf{k}} := \left\{
\begin{array}{ll}
\frac{\hat f_{\mathbf{k}}}{c_{\mathbf{k}} \left(\tilde \varphi\right)} & \text{for
} \mathbf{k} \in I_{\mathbf{N}} , \\[1ex]
0 & \text{for } \mathbf{k} \in I_{\mathbf{n}} \backslash I_{\mathbf{N}} . \\
\end{array}
\right.
\end{equation*}
The values $g_{\mathbf{l}}$ can be obtained by a (multivariate) FFT of size $n_0
\times n_1 \times \hdots \times n_{d-1}$ as
\begin{equation*}
g_{\mathbf{l}} = \frac{1}{\left|I_{\mathbf{n}}\right|}\sum\limits_{\mathbf{k} \in
I_{\mathbf{N}}} \hat g_{\mathbf{k}} \, \eim{\mathbf{k} \left(\mathbf{n}^{-1}\odot \mathbf{l}\right)},
\quad \mathbf{l} \in I_{\mathbf{n}}.
\end{equation*}
Using the compactly supported function $\psi\left(\mathbf{x}\right)=\varphi\left(\mathbf{x}\right)\chi_{[-{m \over n},{m \over
n}]^d}\left(\mathbf{x}\right)$,
one obtains
\begin{equation*}
s\left(\mathbf{x}_j\right) := \sum_{\mathbf{l} \in I_{\mathbf{n},m}\left(\mathbf{x}_j\right) }
g_{\mathbf{l}} \, \tilde\psi\left(\mathbf{x}_j - \mathbf{n}^{-1}\odot\mathbf{l}\right) \, ,
\end{equation*}
where $\tilde \psi$ again denotes the one periodic version of $\psi$ and the
multi-index set is given by
\begin{equation*}
I_{\mathbf{n},m} \left(\mathbf{x}_j\right) := \left\{ \mathbf{l} \in I_{\mathbf{n}} : \mathbf{n}
\odot \mathbf{x}_j - m \mathbf{1} \le \mathbf{l} \le \mathbf{n} \odot \mathbf{x}_j + m
\mathbf{1}\right\}\,.
\end{equation*}
\subsubsection*{The algorithm}
In summary, the following Algorithm~\ref{algo:nfft} is obtained for the fast
computation of \eqref{ndft} with ${\cal O} \left(\left|I_{\mathbf{n}}\right| \log
\left|I_{\mathbf{n}}\right| + m M\right)$ arithmetic operations.

\end{algorithm}
Algorithm~\ref{algo:nfft} reads in matrix vector notation as
\begin{equation*}
\mathbf{A} \mathbf{\hat{f}} \approx \mathbf{B} \mathbf{B} \mathbf{B} \mathbf{\hat{f}},
\end{equation*}
where $\mathbf{B}$ denotes the real $M \times \left|I_{\mathbf{n}}\right|$ sparse matrix
\begin{equation*} \label{spB}
\mathbf{B} := \left( \tilde\psi\left(\mathbf{x}_j - \mathbf{n}^{-1}\odot\mathbf{l}\right)
\right)_{j=0,\hdots,M-1;\, \mathbf{l}\in I_{\mathbf{n}}},
\end{equation*}
where $\mathbf{B}$ is the Fourier matrix of size $\left|I_{\mathbf{n}}\right| \times
\left|I_{\mathbf{n}}\right|$, and where $\mathbf{B}$ is the real $\left|I_{\mathbf{n}}\right|
\times |I_{\mathbf{N}}|$ 'diagonal' matrix
\begin{equation*}
\mathbf{B} := \bigotimes_{t=0}^{d-1} \left(\mathbf{O}_t \, | \, \mbox{diag}\left(1/\,
c_{k_t}\left(\tilde \varphi_t\right)\right)_{k_t\in I_{N_t}} \, | \,
\mathbf{O}_t \right)^{\rm {T}}
\end{equation*}
with zero matrices $\mathbf{O}_t$ of size $N_t \times \frac{n_t-N_t}{2}$.
The corresponding computation of the adjoint matrix vector product reads as
\begin{equation*}
\mathbf{A}^{\adj} \mathbf{\hat{f}} \approx \mathbf{B}^{\top} \mathbf{B}^{\adj} \mathbf{B}^{\top}
\mathbf{\hat{f}} \, .
\end{equation*}
With the help of the transposed index set
\begin{equation*}
I_{\mathbf{n},m}^{\top}\left(\mathbf{l}\right) := \left\{j=0,\hdots,M-1 : \mathbf{l}-m

Due to the characterisation of the nonzero elements of the matrix $\mathbf{B}$,
i.e.,
\begin{equation*}
\bigcup\limits_{j=0}^{M-1} j \times I_{\mathbf{n},m} \left({\mathbf{x}}_j\right)=
\bigcup\limits_{\mathbf{l} \in I_{\mathbf{n}}} I_{\mathbf{n},m}^{\top}\left(\mathbf{l}\right)
\times \mathbf{l}.
\end{equation*}
the multiplication with the sparse matrix $\mathbf{B}^{\top}$ is implemented in a
'transposed' way in the library, summation as outer loop and only using the
multi-index sets $I_{\mathbf{n},m} \left({\mathbf{x}}_j\right)$.

\subsection{Available window functions and evaluation techniques}
\label{sect:windows}
%------------------------------------------------------------------------------
Again, only the case $d=1$ is presented.
To keep the aliasing error and the truncation error small, several functions
$\varphi$ with good localisation in time and frequency domain were proposed,
e.g. the (dilated) {\it Gaussian} \cite{duro93, st97, DuSc}
\begin{eqnarray} \label{gaussian}
\varphi\left(x\right)
&=&
\left(\pi b\right)^{-1/2} \,
{\rm e}^{-\frac{\left(nx\right)^2}{b}}
\qquad
\left(b := \frac{2\sigma}{2 \sigma -1} \frac{m}{\pi} \right),\\
\hat \varphi \left(k\right)
&=&
\frac{1}{n} \, {\rm e}^{-b\left(\frac{\pi k}{n}\right)^2} , \nonumber
\end{eqnarray}
(dilated) {\it cardinal central $B$--splines} \cite{bey95, st97}
\begin{eqnarray} \label{bspline}
\varphi\left(x\right)
&=&
M_{2m}\left(n x\right),\\ \nonumber
\hat \varphi \left(k\right)
&=&
\frac{1}{n} \sinc^{2m} \left( k \pi/n\right),
\end{eqnarray}
where $M_{2m}$ denotes the centred cardinal $B$--Spline of order $2m$,\\
(dilated) {\it Sinc functions} \cite{pottshabil}
\begin{eqnarray} \label{sinc}
\varphi\left(x\right)
&=&
\frac{N\left(2\sigma-1\right)}{2m} \sinc^{2m} \left(\frac{\left(\pi N x \left(2\sigma-1\right)\right)}{2m} \right),\\
\hat \varphi \left(k\right)
&=&
M_{2m}\left(\frac{2mk}{\left(2\sigma-1\right)N}\right)
\nonumber
\end{eqnarray}
and
(dilated) {\it Kaiser--Bessel functions} \cite{Ja, four}
\begin{eqnarray} \label{kaiser}
\varphi\left(x\right)
&=& \frac{1}{\pi} \left\{
\ds \begin{array}{ll}
\ds \frac{\sinh\left(b
\sqrt{m^2 - n^2 x^2}\right)}{\sqrt{m^2 - n^2 x^2}}
& \mbox{for } |x| \le \frac{m}{n}
\qquad
\left(b := \pi \left(2 - \frac{1}{\sigma} \right) \right) ,\\[4ex]
\ds \frac{\sin\left(b
\sqrt{n^2 x^2 - m^2}\right)}{\sqrt{n^2 x^2-m^2}}
& \mbox{otherwise},
\end{array}
\right.
\\[1ex]
\hat \varphi \left(k\right)
&=& \frac{1}{n} \left\{
\ds \begin{array}{cl}
\, I_0 \left(m \sqrt{b^2 - \left(2 \pi k/n \right)^2} \right)
&
{\rm for} \; \; k= -n \left(1-\frac{1}{2\sigma} \right), \ldots,
n \left(1-\frac{1}{2\sigma}\right),\\
0&{\rm otherwise},
\end{array}
\right.
\nonumber
\end{eqnarray}
where $I_0$ denotes the {\it modified zero--order Bessel function}.
For these functions $\varphi$ it has been proven that
$$
|f\left(\mathbf{x}_j\right) - s\left(\mathbf{x}_j\right)| \le C\left(\sigma,m\right) \|\mathbf{\hat{f}}\|_1
$$
where
$$
C\left(\sigma,m\right) :=
\left\{
\begin{array}{ll}
4 \, \e^{-m \pi \left(1-1/\left(2\sigma-1\right)\right)}& {\rm for} \; \left(\ref{gaussian}\right) ,\\
4 \, \left(\frac{1}{2\sigma -1} \right)^{2m}& {\rm for} \; \left(\ref{bspline}\right), \\[1ex]
\frac{1}{m-1}\left(\frac{2}{\sigma^{2m}}+\left(\frac{\sigma}{2\sigma-1}\right)^{2m}\right)&

\right.
$$
Thus, for fixed $\sigma >1$, the approximation error introduced by the NFFT
decays exponentially with the number $m$ of summands in (\ref{approx}).
Using the tensor product approach the above error estimates can be generalised
for the multivariate setting \cite{elst}.
On the other hand, the complexity of the NFFT increases with $m$.
In the following, we suggest different methods for the compressed storage and
application of the matrix $\mathbf{B}$ which are all available within our NFFT
library by choosing particular flags in a simple way during the initialisation
phase.
These methods do not yield a different asymptotic performance but rather yield
a lower constant in the amount of computation.
\subsubsection*{Fully precomputed window function}
One possibility is to precompute all values $\varphi(\mathbf{x}_j -
\mathbf{n}^{-1}\odot\mathbf{l})$ for $j=0,\hdots,M-1$ and $\mathbf{l}\in I_{\mathbf{n},m} (\mathbf{x}_j)$
explicitly.
Thus, one has to store the large amount of $(2m+1)^d M$ real numbers but uses
no extra floating point operations during the matrix vector multiplication
beside the necessary $(2m+1)^d M$ flops.
Furthermore, we store for this method explicitly the row and column for each
nonzero entry of the matrix $\mathbf{B}$.
This method, included by the flag {\tt PRE\_FULL\_PSI}, is the fastest procedure
but can only be used if enough main memory is available.
\subsubsection*{Tensor product based precomputation}
Using the fact that the window functions are built as tensor products one can
store $\varphi_t((\mathbf{x}_j)_t - \frac{l_t}{n_t})$ for
$j=0,\hdots,M-1$, $t=0,\hdots,d-1$, and $l_t\in I_{n_t,m} ((\mathbf{x}_j)_t)$
where $(\mathbf{x}_j)_t$ denotes the $t$-th component of the $j$-th node.
This method uses a medium amount of memory to store $d(2m+1)M$ real numbers
in total.
However, one has to carry out for each node at most $2(2m+1)^d$ extra
multiplications to compute from the factors the multivariate window function
$\varphi(\mathbf{x}_j - \mathbf{n}^{-1}\odot\mathbf{l})$ for $\mathbf{l}\in I_{\mathbf{n},m}(\mathbf{x}_j)$.
%where a naive version would take $d(2m+1)^d$ multiplications.
Note, that this technique is available for every window function discussed
here and can be used by means of the flag {\tt PRE\_PSI} which is also the
default method within our software library.
\subsubsection*{Linear interpolation from a lookup table}
For a large number of nodes $M$, the amount of memory can by further reduced
by the use of lookup table techniques.
For a recent example within the framework of gridding see \cite{BeNiPa05}.
We suggest to precompute from the even window function the equidistant samples
$\varphi_t(\frac{rm}{Kn_t})$ for $t=0,\hdots,d-1$ and $r=0,\hdots,K,\;K\in\N$
and then compute for the actual node $\mathbf{x}_j$ during the NFFT the values
$\varphi_t((\mathbf{x}_j)_t - \frac{l_t}{n_t})$ for $t=0,\hdots,d-1$ and $l_t\in
I_{n_t,m} ((\mathbf{x}_j)_t)$ by means of the linear interpolation from its two
neighbouring precomputed samples.
This method needs only a storage of $dK$ real numbers in total where $K$
depends solely on the target accuracy but neither on the number of nodes $M$
nor on the multidegree $\mathbf{N}$.
Choosing $K$ to be a multiple of $m$, we further reduce the computational
costs during the interpolation since the distance from $(\mathbf{x}_j)_t-
\frac{l_t}{n_t}$ to the two neighbouring interpolation nodes and hence the
interpolation weights remain the same for all $l_t\in I_{n_t,m}((
\mathbf{x}_j)_t)$.
This method requires $2(2m+1)^d$ extra multiplications per node and is
used within the NFFT by the flag {\tt PRE\_LIN\_PSI}. Error estimates for this approximation are given in \cite{KuPo06}.
\subsubsection*{Fast Gaussian gridding}
Two useful properties of the Gaussian window function \eqref{gaussian} within
the present framework were recently reviewed in \cite{GrLe04}.
Beside its tensor product structure for $d>1$, which also holds for all other
window functions, it is remarkable that the number of evaluations of the form
{\tt exp()} can be greatly decreased.
More precisely, for $d=1$ and a fixed node $x_j$ the evaluations of
$\varphi(x_j-\frac{l'}{n})$, $l'\in I_{n,m}(x_j)$, can be reduced by the
splitting
\begin{equation*}
\sqrt{\pi b}\varphi\left(x_j-\frac{l'}{n}\right)
=\e^{-\frac{(nx_j-l')^2}{b}}
=\e^{-\frac{(nx_j-u)^2}{b}}
\left(\e^{-\frac{2(nx_j-u)}{b}}\right)^l
\e^{-\frac{l^2}{b}}\,.
\end{equation*}
where $u=\min I_{n,m}(x_j)$ and $l=0,\hdots,2m$.
Note, that the first factor and the exponential within the brackets are
constant for each fixed node $x_j$.
Once, we evaluate the second exponential, its $l$-th power can be computed
consecutively by multiplications only.
Furthermore, the last exponential is independent of $x_j$ and these $2m+1$
values are computed only once within the NFFT and their amount is negligible.
Thus, it is sufficient to store or evaluate $2M$ exponentials for $d=1$.
The case $d>1$ uses $2dM$ storages or evaluations by using the general tensor
product structure.
This method is employed by the flags {\tt FG\_PSI} and {\tt PRE\_FG\_PSI} for
the evaluation or storage of $2d$ exponentials per node, respectively.
\subsubsection*{No precomputation of the window function}
The last considered method uses no precomputation at all, but rather evaluates
the univariate window function $(2m+1)^d M$ times.
Thus, the computational time depends on how fast we can evaluate the
particular window function.
However, no additional storage is necessary which suits this approach whenever
the problem size reaches the memory limits of the used computer.
%------------------------------------------------------------------------------
\subsection{Further NFFT approaches}
%------------------------------------------------------------------------------
Several papers have described fast approximations for the NFFT.
Common names for NFFT are
{\it non-uniform fast Fourier transform} \cite{fesu02},
{\it generalised fast Fourier transform} \cite{duro93},
{\it unequally-spaced fast Fourier transform} \cite{bey95},
{\it fast approximate Fourier transforms for irregularly spaced data} \cite{ware98},
{\it non-equispaced fast Fourier transform} \cite{Fou02} or
{\it gridding} \cite{scsc, Ja, Pe}.
In various papers, different window functions were considered, e.g. Gaussian
pulse tapered with a Hanning window in \cite{DuSc}, Gaussian kernels combined
with Sinc kernels in \cite{Pe}, and special optimised windows in
\cite{Ja,DuSc}.
A simple but nevertheless fast scheme for the computation of \eqref{ndft} in
the univariate case $d=1$ is presented in \cite{AnDa96}.
This approach uses for each node $x_j \in [-\frac{1}{2},\frac{1}{2})$ a $m$-th
order Taylor expansion of the trigonometric polynomial in \eqref{trigPoly}
about the nearest neighbouring point on the oversampled equispaced lattice
$\{n^{-1} k - \frac{1}{2}\}_{k=0,\hdots,n-1}$ where again $n=\sigma N,\,
\sigma\gg 1$.
Besides its simple structure and only $\cO(N\log N+M)$ arithmetic operations,
this algorithm utilises $m$ FFTs of size $n$ compared to only one in the NFFT
approach, uses a medium amount of extra memory, and is not suited for highly
accurate computations, see \cite{KuPo06}.
Furthermore, its extension to higher dimensions has not been considered so
far.
Another approach for the univariate case $d=1$ is considered in \cite{DuRo95}
and based on a Lagrange interpolation technique.
After taking a $N$-point FFT of the vector $\mathbf{\hat{f}}$ in \eqref{ndft} one
uses an exact polynomial interpolation scheme to obtain the values of the
trigonometric polynomial $f$ at the nonequispaced nodes $x_j$.
Here, the time consuming part is the exact polynomial interpolation scheme
which can however be realised fast in an approximate way by means of the fast
multipole method.
This approach is appealing since it allows also for the inverse transform.
Nevertheless, numerical experiments in \cite{DuRo95} showed that this
approach is far more time consuming than Algorithm \ref{algo:nfft} and the
inversion can only be computed in a stable way for almost equispaced nodes
\cite{DuRo95}.
Furthermore, special approaches based on scaling vectors \cite{NgLi99}, based
on minimising the Frobenius norm of certain error matrices \cite{st01} or
based on min-max interpolation \cite{fesu02} are proposed.
While these approaches gain some accuracy for the Gaussian or B-Spline
windows, no reasonable improvement is obtained for the Kaiser-Bessel window
function.
For comparison of different approaches, we refer to
\cite{ware98,st01,fesu02,KuPo06}.

We consider generalisations of the NFFT for
%------------------------------------------------------------------------------
\subsection{NNFFT - nonequispaced in time and frequency fast Fourier
transform}
%------------------------------------------------------------------------------
Now we are interested in the computation of
\begin{equation*}
f_j= \sum_{k=0}^{N-1} \hat f_k \eim{\left(\mathbf{v}_k \odot \mathbf{N}\right))\mathbf{x}_j}
\end{equation*}
for $j =0,\hdots,M-1$, $\mathbf{v}_k, \mathbf{x}_j \in \T^d$, and $\hat f_k \in \C$, where $\mathbf{N}\in \N^d$
denotes the "nonharmonic" bandwidth.
The corresponding fast algorithm is known as {\it fast Fourier transform for
nonequispaced data in space {\bf and} frequency domain} (NNFFT) \cite{duro93,elst,postta01} or as type 3 nonuniform FFT \cite{LeGr05}.
A straightforward evaluation of this sum with the standard NFFT is not
possible, since the samples in neither domain are equispaced.
However, an so-called NNFFT was first suggested in \cite{duro93} and later
studied in more depth in \cite{elst}, which permits the fast calculation of
the Fourier transform of a vector of nonequispaced samples at a vector of
nonequispaced positions.
It constitutes a combination of the standard NFFT and its adjoint see also
\cite{postta01}.
%------------------------------------------------------------------------------
\subsection{NFCT/NFST - nonequispaced fast (co)sine transform}
%------------------------------------------------------------------------------
Let nonequispaced nodes $\mathbf{x}_j \in [0,\frac{1}{2}]^d$ and frequencies
$\mathbf{k}$ in the index sets
\begin{align*}
I_{\mathbf{N}}^C &:= \left\{ \mathbf{k}=\left(k_t\right)_{t=0,\hdots,d-1} \in \Z^d: 0
\le k_t < N_t ,\;t=0,\hdots,d-1\right\},\\
I_{\mathbf{N}}^S &:= \left\{ \mathbf{k}=\left(k_t\right)_{t=0,\hdots,d-1} \in \Z^d: 1
\le k_t < N_t ,\;t=0,\hdots,d-1\right\}
\end{align*}
be given.
For notational convenience let furthermore $\cos(\mathbf{k} \odot \mathbf{x}) :=
\cos(k_0 x_0) \cdot \hdots \cdot \cos(k_{d-1} x_{d-1})$ and $\sin(\mathbf{k} \odot
\mathbf{x}) := \sin(k_0 x_0) \cdot \hdots \cdot \sin(k_{d-1} x_{d-1})$.
The {\it nonequispaced discrete cosine} and {\it sine transforms} are given by
\begin{align*}
f\left(\mathbf{x}_j\right) &= \sum_{\mathbf{k}\in I_{\mathbf{N}}^C} \hat{f}_{\mathbf{k}}
\cos(2\pi(\mathbf{k}\odot\mathbf{x}_j)),\\
f\left(\mathbf{x}_j\right) &= \sum_{\mathbf{k}\in I_{\mathbf{N}}^S} \hat{f}_{\mathbf{k}}
\sin(2\pi(\mathbf{k}\odot\mathbf{x}_j)),
\end{align*}
for $j=0,\hdots,M-1$ and real coefficients $\hat f_{\mathbf{k}} \in \R$,
respectively.
The straight forward algorithm of this matrix vector product, which is called
ndct and ndst, takes $\cO(M |I_{\mathbf{N}}^C|)$ and $\cO(M |I_{\mathbf{N}}^C|)$
arithmetical operations.
For these real transforms the adjoint transforms coincide with the ordinary
transposed matrix vector products.
Our fast approach is based on the NFFT and seems to be easier than the
Chebyshev transform based derivation in \cite{po01} and faster than the
algorithms in \cite{tili00} which still use FFTs.
Instead of FFTs we use fast algorithms for the discrete cosine transform
(DCT--I) and for the discrete sine transform (DST--I).
For details we refer to \cite{fepo02}.
%------------------------------------------------------------------------------
\subsection{NSFFT - nonequispaced sparse fast Fourier transform}
%------------------------------------------------------------------------------
We consider the fast evaluation of trigonometric polynomials from so-called
hyperbolic crosses.
In multivariate approximation one has to deal with the so called `curse of
dimensionality', i.e., the number of degrees of freedom for representing an
approximation of a function with a prescribed accuracy depends exponentially
on the dimensionality of the considered problem.
This obstacle can be circumvented to some extend by the interpolation on
sparse grids and the related approximation on hyperbolic cross points in the
Fourier domain, see, e.g., \cite{Zeng91,Spr00,BuZe04}.
Instead of approximating a Fourier series on the standard tensor product grid
$I_{\mathbf{(N,\hdots,N)}}$ with $\cO(N^d)$ degrees of freedom, it can be
approximated with only $\cO(N \log^{d-1} N)$ degrees of freedom from the
hyperbolic cross
\begin{equation*}
H_N^d := \bigcup_{\mathbf{N}\in\N^d,\, |I_{\mathbf{N}}|=N} I_{\mathbf{N}},
\end{equation*}
where $N=2^{J+2},\;J\in\NZ$ and we allow $N_t=1$ in the $t$-th coordinate in
the definition of $I_{\mathbf{N}}$.
The approximation error in a suitable norm (dominated mixed smoothness) can be shown to deteriorate only by a factor of $\log^{d-1} N$,
cf. \cite{Spr00}.

\caption{Hyperbolic cross points for $d=2$ and $J=0,\ldots,3$.

\end{figure}
The {\em nonequispaced sparse discrete Fourier transform} (NSDFT) is the
evaluation of
\begin{equation*}
f\left(\mathbf{x}_j\right) = \sum_{\mathbf{k}\in H_N^d}
\hat f_{\mathbf{k}} \eim{\mathbf{k} \mathbf{x}_j}
\end{equation*}
for given Fourier coefficients $\hat f_{\mathbf{k}}\in\C$ and nodes $\mathbf{x}_j\in
\T^d$.
The number of used arithmetical operations is $\cO(M N\log^{d-1}N)$.
This is reduced by our fast schemes to $\cO(N\log^2 N+M)$ for $d=2$ and
$\cO(N^{3/2} \log N+M)$ for $d=3$, see \cite{FeKuPo} for details.
%------------------------------------------------------------------------------
\subsection{FPT - fast polynomial transform} \label{sect:fpt}
%------------------------------------------------------------------------------
A \emph{discrete polynomial transform} (DPT) is a generalisation of the DFT
from the basis of complex exponentials $\mathrm{e}^{\mathrm{i} k x}$ to an
arbitrary systems of algebraic polynomials satisfying a three-term recurrence
relation.
More precisely, let $P_{0},P_{1},\hdots:[-1,1]\rightarrow\R$ be a sequence of
polynomials that satisfies a three-term recurrence relation
\begin{equation*}
P_{k+1}(x) = (\alpha_{k} x + \beta_{k})P_{k}(x) + \gamma_{k} P_{k-1}(x),
\end{equation*}
with $\alpha_{k} \neq 0$, $k\ge 0$, $P_{0}(x) := 1$, and $P_{-1}(x) := 0$.
Clearly, every $P_{k}$ is a polynomial of exact degree $k$ and typical
examples are the classical orthogonal Jacobi polynomials
$P_{k}^{(\alpha,\beta)}$.
Now, let $f:[-1,1]\rightarrow\R$ be a polynomial of degree $N\in\N$ given by
the finite linear combination
\begin{equation*}
f(x) = \sum_{k=0}^{N} a_{k} P_{k}(x).
\end{equation*}
The discrete polynomial transform (DPT) and its fast version, the \emph{fast
polynomial transform} (FPT), are the transformation of the coefficients
$a_{k}$ into coefficients $b_{k}$ from the orthogonal expansion of $f$ into
the basis of Chebyshev polynomials of the first kind $T_{k}(x) := \cos(k
\arccos x)$, i.e.,
\begin{equation*}
f(x) = \sum_{k=0}^N b_{k} T_{k}(x).
\end{equation*}
A direct algorithm for computing this transformation needs $\cO(N^2)$
arithmetic operations.
The FPT algorithm implemented in the NFFT library follows the approach in
\cite{postta98} and is based on the idea of using the three-term-recurrence
relation repeatedly.
Together with a method for fast polynomial multiplication in the Chebyshev
basis and a cascade-like summation process, this yields a method for computing
the polynomial transform with $\cO(N \log^2 N)$ arithmetic operations.
For more detailed information, we refer the reader to
\cite{drhe, drhero, postta98, po01, KePo06} and the references therein.

\subsection{NFSFT - nonequispaced fast spherical Fourier transform}
\label{sect:gen:nfsft}
%------------------------------------------------------------------------------
Fourier analysis on the sphere has, despite other fields, practical
relevance in tomography, geophysics, seismology, meteorology and
crystallography. In analogy to the complex exponentials
$\mathrm{e}^{\mathrm{i} k x}$ on the torus, the spherical harmonics
form the orthogonal Fourier basis with respect to the usual inner product on the sphere.
\subsubsection*{Spherical coordinates}
Every point in $\R^3$ can be described in spherical coordinates by a vector
$(r,\vartheta,\varphi)^{\top}$ with the radius $r\ge 0$ and two angles
$\vartheta \in [0,\pi]$, $\varphi \in [0,2\pi)$.
We denote by $\S^2$ the two-dimensional unit sphere embedded into $\R^3$,
i.e.
\begin{equation*}
\S^2 := \left\{\mathbf{x} \in \R^{3}:\; \|\mathbf{x}\|_2=1\right\}
\end{equation*}
and identify a point from $\S^2$ with the corresponding vector
$(\vartheta,\varphi)^{\top}$.
The spherical coordinate system is illustrated in Figure \ref{sphere}.
\begin{figure}[tb]
\centering
\includegraphics[width=0.60\textwidth]{images/sphere}
\caption{The spherical coordinate system in $\R^3$: Every point $\boldsymbol{\xi}$ on a
sphere with radius $r$ centred at the origin can be described by angles
$\vartheta \in [0,\pi]$, $\varphi \in [0,2\pi)$ and the radius $r \in \mathbb{R}^+$.
For $\vartheta = 0$ or $\vartheta = \pi$ the point $\boldsymbol{\xi}$ coincides with the
North or the South pole, respectively.} \label{sphere}
\end{figure}
\subsubsection*{Legendre polynomials and associated Legendre functions}
The Legendre polynomials $P_k : [-1,1]\rightarrow \R$, $k\ge 0$, as
classical orthogonal polynomials are given by their corresponding Rodrigues
formula
\begin{equation*}
P_k(x) := \frac{1}{2^k k!} \frac{\text{d}^k}{\text{d} x^k}
\left(x^2-1\right)^k.
\end{equation*}
The associated Legendre functions $P_k^n : [-1,1] \rightarrow \R$, $k \ge n
\ge 0$ are defined by
\begin{equation*}
P_k^n(x) := \left(\frac{(k-n)!}{(k+n)!}\right)^{1/2}
\left(1-x^2\right)^{n/2} \frac{\text{d}^n}{\text{d} x^n} P_k(x).
\end{equation*}
For $n = 0$, they coincide with the Legendre polynomials $P_k = P_k^0$.
The associated Legendre functions $P_{k}^n$ obey the three-term recurrence
relation
\begin{equation*}
P_{k+1}^n(x) = \frac{2k+1}{((k-n+1)(k+n+1))^{1/2}} x P_k^n(x) -
\frac{((k-n)(k+n))^{1/2}}{((k-n+1)(k+n+1))^{1/2}} P_{k-1}^n(x)
\end{equation*}
for $k \ge n \ge 0$, $P_{n-1}^n(x) = 0$, $P_{n}^n(x) = \frac{\sqrt{(2n)!}}{2^n
n!}\left(1-x^2\right)^{n/2}$.
For fixed $n$, the set $\{P_k^n:\: k \ge n\}$ forms a set of
orthogonal functions, i.e.,
\begin{equation*}
\left\langle P_k^n,P_l^n \right\rangle =
\int_{-1}^{1} P_k^n(x) P_l^n(x) \text{d} x =
\frac{2}{2k+1} \delta_{k,l}.
\end{equation*}
Again, we denote by $\bar{P}_{k}^n = \sqrt{\frac{2k+1}{2}} P_k^n$ the
orthonormal associated Legendre functions.
In the following, we allow also for $n < 0$ and set $P_{k}^n$ := $P_{k}^{-n}$
in this case.
\subsubsection*{Spherical harmonics}
The spherical harmonics $Y_k^n : \S^2 \rightarrow \C$, $k \ge |n|$, $n\in\Z$,
are given by
\begin{equation*}
Y_k^n(\vartheta,\varphi) := P_k^{n}(\cos\vartheta)
\, \mathrm{e}^{\mathrm{i} n \varphi}.
\end{equation*}
They form an orthogonal basis for the space of square integrable functions on
the sphere, i.e.,
\begin{equation*}
\left\langle Y_k^n,Y_l^m \right\rangle =
\int_{0}^{2\pi} \int_{0}^{\pi} Y_k^n(\vartheta,\varphi)
\overline{Y_l^m(\vartheta,\varphi)} \sin \vartheta \; \mathrm{d} \vartheta
\; \mathrm{d} \varphi =
\frac{4\pi}{2k+1} \delta_{k,l}\delta_{n,m}.
\end{equation*}
The orthonormal spherical harmonics are denoted by $\bar{Y}_k^n =
\sqrt{\frac{2k+1}{4\pi}} Y_k^n$.
Hence, any square integrable function $f:\S^2\rightarrow\C$ has the expansion
\begin{equation*}
f = \sum_{k=0}^{\infty} \sum_{n=-k}^{k} \hat{f}(k,n) \bar{Y}_k^n,
\end{equation*}
with the spherical Fourier coefficients $\hat{f}(k,n) = \left\langle f,
\bar{Y}_k^n \right\rangle$.
The function $f$ is called \emph{bandlimited}, if $\hat{f}(k,n)=0$ for $k>N$
and some $N\in\N$.
In analogy to the NFFT on the Torus $\mathbb{T}$, we define the sampling set
\begin{equation*}
\mathcal{X}: = \left\{\left(\vartheta_{j},\varphi_{j}\right) \in
\mathbb{S}^2:\,j=0,\hdots,M-1\right\}
\end{equation*}
of nodes on the sphere $\S^2$ and the set of possible ''frequencies''
\begin{equation*}
\mathcal{I}_{N} := \left\{(k,n):\,k=0,1,\ldots,N;\;
n=-k,\ldots,k\right\}.
\end{equation*}
The \emph{nonequispaced discrete spherical Fourier transform} (NDSFT) is
defined as the evaluation of the finite spherical Fourier sum
\begin{equation}
\label{eq.ndsft}
f_j=
f\left(\vartheta_{j},\varphi_{j}\right) =
\sum_{(k,n) \in \, \mathcal{I}_{N}} \hat{f}_k^n \,
Y_k^n\left(\vartheta_{j},\varphi_{j}\right) =
\sum_{k=0}^N \sum_{n=-k}^k \hat{f}_k^n \,
Y_k^n\left(\vartheta_{j},\varphi_{j}\right)
\end{equation}
for $j=0,\hdots,M-1$.
In matrix vector notation, this reads $\mathbf{f} = \mathbf{Y} \; \mathbf{\hat
f}$ with
\begin{equation*}
\begin{split}
\mathbf{f} & := \left(f_j\right)_{j=0}^{M-1} \in
\mathbb{C}^{M},\ f_{j} := f\left(\vartheta_{j},\varphi_{j}\right),\\
\mathbf{Y} & :=
\left(Y_k^n\left(\vartheta_j,\varphi_j\right)\right)_{j=0,\ldots,M-1;\;
(k,n) \in \mathcal{I}_N} \in \mathbb{C}^{M \times (N+1)^2},\\
\mathbf{\hat f} & := \left(\hat f_k^n\right)_{(k,n) \in \mathcal{I}_N} \in
\mathbb{C}^{(N+1)^2}.
\end{split}
\end{equation*}
The corresponding \emph{adjoint nonequispaced
discrete fast spherical Fourier transform} (adjoint NDSFT) is defined as
the evaluation of
\begin{equation*}
\label{eq.adjointndsft}
\hat h_{k}^n =
\sum_{j = 0}^{M-1} f\left(\vartheta_{j},\varphi_{j}\right)
\overline{Y_k^n\left(\vartheta_{j},\varphi_{j}\right)}
\end{equation*}
for all $(k,n) \in \mathcal{I}_{N}$.
Again, in matrix vector notation, this reads $\mathbf{\hat h} =
\mathbf{Y}^{\adj} \, \mathbf{f}$.
The coefficients $\hat h_{k}^n$ are, in general, not
identical to the Fourier coefficients $\hat{f}(k,n)$ of the function $f$.
However, provided that for the sampling set $\mathcal{X}$ a quadrature rule
with weights $w_{j}$, $j=0,\hdots,M-1$, and sufficient degree of exactness
is available, one might recover the Fourier coefficients $\hat{f}(k,n)$ by
evaluating
\begin{equation*}
\hat{f}_{k}^n = \int_{0}^{2\pi} \int_{0}^{\pi} f(\vartheta,\varphi)
\overline{Y_{k}^n(\vartheta,\varphi)} \sin\vartheta \; \mathrm{d} \vartheta
\; \mathrm{d} \varphi =
\sum_{j = 0}^{M-1} w_{j} f\left(\vartheta_{j},\varphi_{j}\right)
\overline{Y_k^n\left(\vartheta_{j},\varphi_{j}\right)}
\end{equation*}
for all $(k,n) \in \mathcal{I}_{N}$.
Direct algorithms for computing the NDSFT and adjoint NDSFT transformations
need $\cO(M N^2)$ arithmetic operations.
A combination of the fast polynomial transform and the NFFT leads to
approximate algorithms with $\cO(N^2 \log^2 N + M)$ arithmetic operations.
These are denoted \emph{NFSFT} and \emph{adjoint NFSFT}, respectively.
The NFSFT algorithm using the FPT and the NFFT was introduced in
\cite{kupo02} while the adjoint NFSFT variant was developed in \cite{KePo06}.

\subsection{Solver - inverse transforms} \label{sect:inv}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
In the following, we describe the inversion of the NFFT, i.e., the computation
of Fourier coefficients from given samples $(\mathbf{x}_j,y_j) \in \T^d\times \C$,
$j=0,\ldots,M-1$.
In matrix vector notation, we aim to solve the linear system of equations
\begin{equation}\label{eq:infft}
\mathbf{A} \mathbf{\hat{f}} \approx \mathbf{y}
\end{equation}
for the vector $\mathbf{\hat{f}}\in\C^{|I_{\mathbf{N}|}}$.
Note however that the nonequispaced Fourier matrix $\mathbf{A}$ can be replaced by
any other Fourier matrix from Section \ref{sect:gen}.
Typically, the number of samples $M$ and the dimension of the space of the
polynomials $|I_{\mathbf{N}}|$ do not coincide, i.e., the matrix $\mathbf{A}$ is
rectangular.
There are no simple inverses to nonequispaced Fourier matrices in general and
we search for some pseudoinverse solution $\mathbf{\hat{f}}^{\dagger}$, see
e.g. \cite[p. 15]{Bj96}.
However, we conclude from eigenvalue estimates in
\cite{FeGrSt95,BaGr03,KuPo04} that the matrix $\mathbf{A}$ has full rank if
\begin{equation*}
\max_{0\le tC_d q^{-1}\,, \qquad q:=\min_{0\le j 0$, $\mathbf{W}:=\diag(w_j)_{j=0,\hdots,M-1}$,
to compensate for clusters in the sampling set ${\cal X}$.
This least squares problem is equivalent to the
{\em weighted normal equation of first kind}
\begin{equation}\label{eq:no1}
\mathbf{A}^{\adj} \mathbf{W} \mathbf{A} \mathbf{\hat{f}} = \mathbf{A}^{\adj} \mathbf{W} \mathbf{y}.
\end{equation}
Applying the Landweber (also known as Richardson, ...), the steepest descent,
or the conjugate gradient scheme to \eqref{eq:no1} yields the following

\subsubsection*{Interpolation}
%------------------------------------------------------------------------------
For a comparative high polynomial degree $|I_{\mathbf{N}}|>M$ one expects to
interpolate the given data $y_j\in \C,\;j=0,\hdots,M-1,$ exactly.
The (consistent) linear system \eqref{eq:infft} is under-determined.
One considers the {\em damped minimisation problem}
\begin{equation*}
\label{eq:ip}
\|\mathbf{\hat{f}}\|_{\mathbf{\hat{W}}}^{-1}
=\left(\sum_{\mathbf{k}\in I_{\mathbf{N}}} \frac{|\hat f_{\mathbf{k}}|^2}{\hat w_{\mathbf{k}}}
\right)^{1/2} \stackrel{\mathbf{\hat{f}}}{\rightarrow} \min \quad \text{subject
to} \quad \mathbf{A} \mathbf{\hat{f}} = \mathbf{y},
\end{equation*}
which may incorporate 'damping factors' $\hat w_{\mathbf{k}}> 0$, $\mathbf{\hat{W}}:=
\diag(\hat w_{\mathbf{k}})_{\mathbf{k}\in I_{\mathbf{N}}}$.
A smooth solution is favoured, i.e., a decay of the Fourier coefficients $\hat
f_{\mathbf{k}},\;\mathbf{k}\in I_{\mathbf{N}}$, for decaying damping factors $\hat w_{
\mathbf{k}}$.
This interpolation problem is equivalent to the
{\em damped normal equation of second kind}
\begin{equation} \label{eq:no2}
\mathbf{A} \mathbf{\hat{W}} \mathbf{A}^{\adj} \mathbf{\tilde{f}}
= \mathbf{y}, \qquad \mathbf{\hat{f}} =
\mathbf{\hat{W}} \mathbf{A}^{\adj} \mathbf{\tilde{f}}.
\end{equation}
Applying the conjugate gradient scheme to \eqref{eq:no2} yields the following
Algorithm \ref{algo:wCGNE(R)}.

\section{Library}\label{sect:lib}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
The library is completely written in C and uses the FFTW library \cite{fftw}
which has to be installed on your system.
The library has several options (determined at compile time) and parameters
(determined at run time).
%------------------------------------------------------------------------------
\subsection{Installation}
%------------------------------------------------------------------------------
Download from {\tt www.tu-chemnitz.de/$\sim$potts/nfft} the most recent
version {\tt nfft3.x.x.tgz}. In the following, we assume that you use a \verb+bash+
compatible shell.
Uncompress the archive.
\begin{itemize}
\item \verb"tar xfvz nfft3.x.x.tar.gz"
\end{itemize}
Change to the newly created directory.
\begin{itemize}
\item \verb+cd nfft3.x.x+
\end{itemize}
Optional: Set environment variables (see also below).
Leave this step out, if you are unsure what to do.
Example:
\begin{itemize}
\item \verb+export CPPFLAGS="-I/path/to/include/files"+\\
\item \verb+export LDFLAGS="-L/path/to/libraries"+
\end{itemize}
Run the configure script.
\begin{itemize}
\item \verb+./configure+
\end{itemize}
Compile the sources.
\begin{itemize}
\item \verb+make+
\end{itemize}
This builds the NFFT library and all examples and applications. You can run
\verb"make install" to install the library on your system. If
for example \verb+/usr+ is your default installation directory, \verb+make install+
will copy the NFFT 3 library to \verb+/usr/lib+, the C header files to
\verb+/usr/include/nfft+ and the documentation together with all examples and
applications to \verb+/usr/share/nfft+.
For more information on fine grained
control over the installation directories, run the \verb"configure" script
with the option \verb+--help+, i.e. \verb+./configure --help+.
For example, to see what gets installed, run
\verb+./configure --prefix=some/path/to/a/temporary/directory+ in the line of
commands above. After \verb+make+ and \verb+make install+, you will find all
installed files in the directory structure created under the temporary directory.
The following options can also be used in conjunction with the configure script:
By default, NFFT 3 routines use the Kaiser-Bessel window function
(see Appendix \ref{sec.nfft}). You can
change the window function with the option \verb"--with-window=ARG",
where \verb"ARG" is replaced by \verb"kaiserbessel" (Kaiser-Bessel),
\verb"gaussian" (Gaussian), \verb"bspline" (B-spline),
\verb"sinc" (sinc power) or \verb"delta" (Dirac delta) to yield the
window function in parenthesis.
The NFFT transforms can be configured to measure elapsed
time for each step of Algorithm~\ref{algo:nfft} and \ref{algo:nfftH}.
This should help customise the library to one's needs.
You can enable this behaviour with
the options \verb"--enable-measure-time" and/or
\verb"--enable-measure-time-fftw".
%------------------------------------------------------------------------------
\subsection{Procedure for computing an NFFT}\label{sect:general_proc}
%------------------------------------------------------------------------------
One has to follow certain steps to write a simple program using the NFFT
library.
A complete example is shown in Section \ref{sect:first_trafo}.
The first argument of each function is a pointer to a application-owned
variable of type {\tt nfft\_plan}.
The aim of this structure is to keep interfaces small, it contains all
parameters and data.
\subsubsection*{Initialisation}
Initialisation of a plan is done by one of the {\tt nfft\_init}-functions.
The simplest version for the univariate case $d=1$ just specifies the number
of Fourier coefficients $N_0$ and the number of nonequispaced nodes $M$.
For an application-owned variable {\tt nfft\_plan my\_plan} the function call is
\begin{center}
{\tt nfft\_init\_1d(\&my\_plan,N0,M);}
\end{center}
The first argument should be uninitialised. Memory allocation is completely
done by the init routine.
\subsubsection*{Setting nodes}
One has to define the nodes $\mathbf{x}_j \in \T^d$ for the
transformation in the member variable {\tt my\_plan.x}.
The $t$-th coordinate of the $j$-th node $\mathbf{x}_j$ is assigned by
\begin{center}
{\tt my\_plan.x[d*j+t]= /* your choice in [-0.5,0.5] */;}
\end{center}
\subsubsection*{Precompute $\tilde\psi$}
The precomputation of the values $\tilde\psi\left({\mathbf{x}}_j - \mathbf{n}^{-1}\odot
\mathbf{l}\right)$, i.e. the entries of the matrix $\mathbf{B}$, depends on the choice
for {\tt my\_plan.x}.
If one of the proposed precomputation strategies ({\tt PRE\_LIN\_PSI}, {\tt
PRE\_FG\_PSI}, {\tt PRE\_PSI}, or {\tt PRE\_FULL\_PSI}) is used, one has to call
the appropriate precomputation routine {\bf AFTER} setting the nodes.
For simpler usage this has been summarised by
\begin{center}
{\tt if(my\_plan.nfft\_flags \& PRE\_ONE\_PSI)
nfft\_precompute\_one\_psi(\&my\_plan);}
\end{center}
Note furthermore, that
\begin{enumerate}
\item {\tt FG\_PSI} and {\tt PRE\_FG\_PSI} rely on the Gaussian window
function,
\item {\tt PRE\_LIN\_PSI} is actual node independent and in this case the
precomputation can be done before setting nodes,
\item {\tt PRE\_FULL\_PSI} asks for quite a bit of memory.
\end{enumerate}
\subsubsection*{Doing the transform}
Algorithm \ref{algo:nfft} is implemented as
\begin{center}
{\tt nfft\_trafo(\&my\_plan);}
\end{center}
takes {\tt my\_plan.f\_hat} as its input and overwrites {\tt my\_plan.f}.
One only needs one plan for several transforms of the same kind,
i.e. transforms with equal initialisation parameters.
For comparison, the direct calculation of \eqref{ndft} is done by
{\tt ndft\_trafo}.
The adjoint transforms are given by {\tt nfft\_adjoint} and {\tt
ndft\_adjoint}, respectively.
All data with multi-indices is stored plain, in particular the Fourier
coefficient $\hat f_{\mathbf{k}}$ is stored in {\tt my\_plan.f\_hat[k]} with
${\text{\tt k}}:=\sum_{t=0}^{d-1} (k_t+\frac{N_t}{2}) \prod_{t'=t+1}^{d-1}
N_{t'}$.
Data vectors might be exchanged by
\begin{center}
{\tt NFFT\_SWAP\_complex(my\_plan.f\_hat,new\_f\_hat);}.
\end{center}
\subsubsection*{Finalisation}
All memory allocated by the init routine is deallocated by
\begin{center}
{\tt nfft\_finalize(\&my\_plan);}
\end{center}
Note, that almost all (de)allocation operations of the library are done by
{\tt fftw\_malloc} and {\tt fftw\_free}.
Additional data, declared and allocated by the application, have to be
deallocated by the user's program as well.
\subsubsection*{Data structure and functions}
The library defines the structure {\tt nfft\_plan}, the most important
members are listed in Table \ref{table:nfft_members}.
Moreover, the user functions for the NFFT are collected in Table
\ref{table:nfft_user_fun}.
They all have return type {\tt void} and their first argument is of type {\tt
nfft\_plan*}.

%------------------------------------------------------------------------------
\subsection{Generalisations and nomenclature}
%------------------------------------------------------------------------------
The generalisations to the nonequispaced FFT in time and frequency domain, the
nonequispaced fast (co)sine transform, and the nonequispaced sparse FFT are
based on the same procedure as the NFFT.
In the following we give some more details for the nonequispaced fast
spherical Fourier transform.
\subsubsection*{NFSFT}
Compared to the NFFT routines, the NFSFT module shares a similar basic
procedure for computing the transformations. It differs, however, slightly
in data layout and function interfaces.
The NFSFT routines depend on initially precomputed global data that limits the
maximum degree \verb"N" that can be used for computing transformations. This
precomputation has to be performed only once at program runtime regardless of
how many individual transform plans are used throughout the rest. This is done
by
\begin{center}
\verb"nfsft_precompute(N,1000,0U,0U);"
\end{center}
Here, \verb"N" is the maximum degree that can be used in all subsequent transformations,
\verb"1000" is the threshold for the FPTs used internally, and
\verb"0U" and \verb"0U" are optional flags for the NFSFT and FPT. If you
are unsure which values to use, leave the threshold at \verb"1000" and
the flags at \verb"0U".
Initialisation of a plan is done by calling one of the
\verb"nfsft_init"-functions. We need no dimension parameter here, as in
the NFFT case. The simplest version is a call to \verb"nfsft_init"
specifying only the bandwidth $N$ and the number of nonequispaced nodes $M$.
For an application-owned variable \verb"nfsft_plan my_plan" the function call
is
\begin{center}
\verb"nfsft_init(&my_plan,N,M);"
\end{center}
The first argument should be uninitialised. Memory allocation is completely
done by the init routine.
After initialising a plan, one defines the nodes $(\vartheta_{j},\varphi_{j}) \in
[0,2\pi) \times [0,\pi]$ in spherical coordinates in the member variable
\verb"my_plan.x".
For consistency with the other modules and the conventions used there, we
use swapped and scaled spherical coordinates
\begin{align*}
\tilde{\varphi} & :=
\left\{
\begin{array}{ll}
\frac{\varphi}{2\pi}, & \text{if $0 \le \varphi < \pi$}, \\[1ex]
\frac{\varphi}{2\pi}-1, & \text{if $\pi \le \varphi < 2\pi$},
\end{array}
\right. & \tilde{\vartheta} & := \frac{\vartheta}{2\pi}
\end{align*}
and identify a point from $\mathbb{S}^2$ with the vector
$(\tilde{\varphi}, \tilde{\vartheta}) \in
[-\frac{1}{2}, \frac{1}{2}) \times [0,\frac{1}{2}]$.
The angles $\tilde{\varphi}_{j}$ and $\tilde{\vartheta}_{j}$ for
the $j$-th node are assigned by
\begin{center}
\begin{minipage}{10cm}
\verb"my_plan.x[2*j] = /* your choice in [-0.5,0.5] */;"
\verb"my_plan.x[2*j+1] = /* your choice in [0,0.5] */;"
\end{minipage}
\end{center}
After setting the nodes, the same node-dependent (see the exception above)
precomputation as for the NFFT has to be performed.
This is done by
\begin{center}
\verb"nfsft_precompute_x(&my_plan);"
\end{center}
which itself calls \verb"nfft_precompute_one_psi(&my_plan)" as explained above. You might modify
the precomputation strategy by passing the appropriate NFFT flags to one of the
more advanced \verb"nfsft_init" routines.
Setting the spherical Fourier coefficients $\hat{f}_{k}^n$ in \verb+my_plan.f_hat+
should be done using the helper macro \verb+NFSFT_INDEX+. This reads
\begin{center}
\begin{minipage}{11cm}
\verb"for (k = 0; k <= N; k++)" \\
% \verb"{" \\
\verb" for (n = -k; n <= k; n++)" \\
% \verb" {" \\
\verb" my_plan.f_hat[NFSFT_INDEX(k,n,&plan)] = /* your choice */;" \\
% \verb" }"\\
% \verb"}"
\end{minipage}
\end{center}
For the NFSFT, spherical Fourier coefficients are stored in a fashion different from
the NFFT. You should always use the helper macro \verb+NFSFT_INDEX+ for setting
the spherical Fourier coefficients. If, in place of a NFSFT transformation, you
would like to perform an adjoint NFSFT transformation, you set
the values $f\left(\vartheta_{j}, \varphi_{j}\right)$ in \verb+my_plan.f+ as follows:
\begin{center}
\begin{minipage}{11cm}
\verb"for (j = 0; j < M; j++)" \\
% \verb"{" \\
\verb" my_plan.f[j] = /* your choice */;" \\
% \verb"}"
\end{minipage}
\end{center}
The actual transforms are computed by calling either \verb+nfsft_trafo(&my_plan)+
for the NFSFT (see Algorithm \ref{NFSFT:Algorithm:NFSFT}) or
\verb+nfsft_adjoint(&my_plan)+ for the adjoint NFSFT (see Algorithm
\ref{NFSFT:Algorithm:adjointNFSFT}).
Remember, that you must make sure that \verb+my_plan.x+ and \verb+my_plan.f_hat+
or \verb+my_plan.f+ have been initialised appropriately prior to calling the
corresponding transformation routine.
On execution, \verb+nfsft_trafo+ overwrites \verb+my_plan.f+ while
\verb+nfsft_adjoint+ overwrites \verb+my_plan.f_hat+.
One only needs one plan for several transforms of the same kind,
i.e. transforms with equal initialisation parameters.
For comparison, the direct calculation of \eqref{eq.ndsft} and \eqref{eq.adjointndsft}
are done by \verb+ndsft_trafo+ and \verb+ndsft_adjoint+, respectively.
All memory allocated by the init routine is deallocated by
\begin{center}
\verb+nfsft_finalize(&my_plan);+
\end{center}
while the memory allocated by \verb+nfsft_precompute+ gets
freed by calling
\begin{center}
\verb+nfsft_forget();+
\end{center}
Additional data, declared and allocated by the application, has to be
deallocated by the user's program as well.
The library defines the structure \verb+nfsft_plan+, the most important
members are listed in Table \ref{table:nfsft_members}.
The structure contains, public read-only (r) and public read-write (w)
members.
The user functions for the NFSFT are collected in Table
\ref{table:nfsft_user_fun}.

Some more things should be kept in mind when using the NFSFT module:
\begin{itemize}
\item The bandwidth $N_{\text{max}}$ up to which global precomputation is
performed when calling \verb+nfsft_precompute+ is always chosen as the
next power of two with respect to the specified maximum bandwidth $N$.
\item By default, the NDSFT and NFSFT transformations,
\verb+ndsft_trafo+ and \verb+nfsft_trafo+, are allowed to destroy the
input \verb+f_hat+ while the input \verb+x+ is preserved. On the contrary,
the adjoint NDSFT and NFSFT transformations, \verb+ndsft_adjoint+ and
\verb+nfsft_adjoint+, do not destroy the input \verb+f+ and \verb+x+ by
default. The desired behaviour can be assured by using the
\verb+NFSFT_PRESERVE_F_HAT+, \verb+NFSFT_PRESERVE_X+, \verb+NFSFT_PRESERVE_F+ and
\verb+NFSFT_DESTROY_F_HAT+, \verb+NFSFT_DESTROY_X+, \verb+NFSFT_DESTROY_F+
flags.

\subsection{Inversion and solver module} \label{sect:general_proc_infft}
%------------------------------------------------------------------------------
The flow chart in Figure \ref{fig:struct} shows how to use the inverse
transforms as implemented in the solver module of the library.
There is no general stopping rule implemented, since this task is highly
dependent on the particular application.
\begin{figure}[ht!]
\begin{center}
\input{struct}
\end{center}
\caption{Flow chart of the inverse transforms.\label{fig:struct}}
\end{figure}
Each inverse transform basically wraps an already initialised Fourier
transform.
The user specifies one of the Algorithms
\ref{algo:landweber}-\ref{algo:wCGNE(R)} by setting one of the flags
({\tt LANDWEBER}, {\tt STEEPEST\_DESCENT}, {\tt CGNR}, {\tt CGNE}).
Weights and/or damping factors are used if the flags {\tt
PRECOMPUTE\_WEIGHT}, {\tt PRECOMPUTE\_DAMP} are set and one has to initialise
the members {\tt my\_iplan.w}, {\tt my\_iplan.w\_hat} in these cases.
Default flags are {\tt CGNR}.
In case of the NFFT, the library defines the structure {\tt infft\_plan}.
The members of this plan are given by Table \ref{table:infft_members}.
The user functions for the inverse NFFT are collected in Table
\ref{table:infft_user_fun}.
They all have return type {\tt void} and their first argument is of type {\tt
infft\_plan*}.
Replacing {\tt nfft} by any other Fourier transform gives the appropriate
inverse to this transform.

The library was tested on a AMD Athlon(tm) XP 2700+, 1GB memory, SuSe-Linux,
kernel 2.4.20-4GB-athlon, gcc version 3.3.
In all tests with random input the nodes $\mathbf{x}_j$ and the Fourier
coefficients $\hat f_{\mathbf{k}}$ are chosen pseudo randomly with $\mathbf{x}_j \in
[-0.5,0.5]^d$ and $\hat f_{\mathbf{k}} \in [0,1] \times [0,1]{\rm i}$.

\subsection{Computing your first transform}\label{sect:first_trafo}
%------------------------------------------------------------------------------
The following code summarises the steps of Section \ref{sect:general_proc} and
computes a univariate NFFT from 14 Fourier coefficients and 19 nodes.
Note that this routine is part of {\tt simple\_test.c} in {\tt examples/nfft/}
and uses additional routines as defined {\tt include/util.h} to set up and
show vectors.
\begin{verbatim}
void simple_test_nfft_1d()
{
nfft_plan p;
int N=14;
int M=19;
nfft_init_1d(&p,N,M);
nfft_vrand_shifted_unit_double(p.x,p.M_total);
if(p.nfft_flags & PRE_ONE_PSI)
nfft_precompute_one_psi(&p);
nfft_vrand_unit_complex(p.f_hat,p.N_total);
nfft_vpr_complex(p.f_hat,p.N_total,"given Fourier coefficients, f_hat");
ndft_trafo(&p);
nfft_vpr_complex(p.f,p.M_total,"ndft, f");
nfft_trafo(&p);
nfft_vpr_complex(p.f,p.M_total,"nfft, f");
nfft_finalize(&p);
}
\end{verbatim}
%------------------------------------------------------------------------------
\subsection{Computation time vs. problem size}
%------------------------------------------------------------------------------
The program {\tt nfft\_times} in the same directory compares the computation
time of the FFT (\cite{fftw}, {\tt FFTW\_MEASURE}), the straightforward
evaluation of \eqref{eq:nfft}, denoted by NDFT, and the NFFT for increasing
total problem sizes $|I_{\mathbf{N}}|$ and space dimensions $d=1,2,3$, where $
\mathbf{N}=(N,\hdots,N)^{\top},\;N\in\N$.
While the nodes for the FFT are restricted to the lattice $\mathbf{N}^{-1}\odot
I_{\mathbf{N}}$, we choose $M=N^d$ random nodes for the NDFT and the NFFT.
Within the latter, we use the oversampling factor $\sigma=2$, the cut-off
$m=4$, and the Kaiser-Bessel window function ({\tt PRE\_PSI}, {\tt
PRE\_PHI\_HUT}).
This results in a fixed accuracy of $E_{\infty}:=\|\mathbf{f}-
\mathbf{s}\|_{\infty}/\|\mathbf{\hat{f}}\|_1\approx 10^{-8}$ for $d=1,2,3$.

\caption{Computation time in seconds with respect to $l_N=\log_2|I_{

Note that we used accumulated measurements in case of small times and the

to the FFT time.}
\label{tab:TimeSpace_1}
\end{table}
We conclude the following: The FFT and the NFFT show the expected
$\cO(|I_{\mathbf{N}}|\log|I_{\mathbf{N}}|)$ time complexity, i.e., doubling the total size $|I_{\mathbf{N}}|$
results in only slightly more than twice the computation time, whereas the
NDFT behaves as $\cO(|I_{\mathbf{N}}|^2)$.
Note furthermore, that the constant in the $\cO$-notation is independent of
the space dimension $d$ for the FFT and the NDFT, whereas the computation time
of the NFFT increases considerably for larger $d$.
%------------------------------------------------------------------------------
\subsection{Accuracy vs. window function and cut-off parameter $m$}
%------------------------------------------------------------------------------
The accuracy of the Algorithm \ref{algo:nfft}, measured by
\begin{equation*}
E_2=\frac{\|\mathbf{f}- \mathbf{s}\|_2}{\|\mathbf{f}\|_2}
=\left({\sum_{j=0}^{M-1}|f_j-s\left(
\mathbf{x}_j\right)|^2}/{\sum_{j=0}^{M-1}
|f_j|^2}\right)^{\frac{1}{2}}
\end{equation*}
and
\begin{equation*}
E_{\infty}=\frac{\|\mathbf{f}- \mathbf{s}\|_{\infty}}{\|\mathbf{\hat{f}}\|_1}
={\max_{0\le j0$, e.g. the Gaussian
$K(x)=\e^{-x^2/c^2}$, the multiquadric $K(x)=\sqrt{x^2+c^2}$ or the inverse
multiquadric $K(x)=1/\sqrt{x^2+c^2}$ our algorithm requires $\cO(N+M)$
arithmetic operations.
In the case of singular kernels $K$, e.g.,
\begin{equation*}
\frac{1}{x^2},\; \frac{1}{|x|}, \; \log |x|, \;
x^2 \log |x|, \; \frac{1}{x}, \;
\frac{\sin(c x)}{x},\; \frac{\cos(c x)}{x}, \; \cot(cx)
\end{equation*}
an additional regularisation procedure must be incorporated and the algorithm
has the arithmetic complexity $\cO(N \log N +M)$ or $\cO(M\log M + N)$ if
either the target nodes $\mathbf{y}_j$ or the source nodes $\mathbf{x}_k$ are
``reasonably uniformly distributed''.
Note that the proposed fast algorithm \cite{post02,postni04,FeSt03}
generalises the diagonalisation of convolution matrices by Fourier matrices to
the setting of arbitrary nodes.
In particular, this yields nearly the same arithmetic complexity as the FMM
\cite{beatgreen97} while allowing for an easy change of various kernels.
A recent application in particle simulation is given in \cite{popori05}.
The directory {\tt applications/fastsum} contains C and {\sc MatLab} programs
that show how to use the fast summation method.
%------------------------------------------------------------------------------
\subsection{Fast Gauss transform}
%------------------------------------------------------------------------------
This is a special case of the fast summation method, we compute approximations
of the following sums.
Given complex coefficients $\alpha_k \in \C$ and source nodes
$x_k\in[-\frac{1}{4},\frac{1}{4}]$, our goal consists in the fast evaluation
of the sum
\begin{equation*}
g\left(y\right)=\sum_{k=1}^N \alpha_k {\rm e}^{-\sigma|y-x_k|^2}
\end{equation*}
at the target nodes $y_j \in [-\frac{1}{4},\frac{1}{4}]$, $j=1,\ldots,M$,
where $\sigma =a +{\rm i} b$, $a>0$, $b\in\R$, denotes a complex parameter.
For details see \cite{KuPoSt06} and the related paper \cite{AnBe04} for
applications.
All numerical examples of \cite{KuPoSt06} are produced by the programs in {\tt
applications/fastgauss}.
%------------------------------------------------------------------------------
\subsection{Summation of zonal functions on the sphere}
%------------------------------------------------------------------------------
Given $M,N \in \N$, arbitrary source nodes $\mathbf{\eta}_k \in \S^2$ and real
coefficients $\alpha_k\in\R$, evaluate the sum
\begin{equation*}
g\left(\mathbf{\xi}\right) := \sum_{k = 1}^N \alpha_k K\left(\mathbf{\eta}_k \cdot
\mathbf{\xi}\right)
\end{equation*}
at the target nodes $\mathbf{\xi}_j\in\S^2$, $j=1,\hdots,M$.
The naive approach for evaluating this sum takes $\cO(MN)$ floating point
operations if we assume that the zonal function $K$ can be evaluated in
constant time or that all values $K(\mathbf{\eta}_k \cdot \mathbf{\xi}_j)$ can be stored
in advance.
In contrast, our scheme is based on the nonequispaced fast spherical Fourier
transform, has arithmetic complexity $\cO(M+N)$, and can be easily adapted to
such different kernels $K$ as
\begin{enumerate}
\item the Poisson kernel
$Q_{h}:[-1,1] \rightarrow \R$ with $h \in (0,1)$ given by
\[
Q_{h}(x) := \frac{1}{4\pi} \frac{1-h^2}{\left(1-2 h x+h^2\right)^{3/2}},
\]
\item the singularity kernel
$S_{h}:[-1,1] \rightarrow \R$ with $h \in (0,1)$ given by
\[
S_{h}(x) := \frac{1}{2\pi} \frac{1}{\left(1-2 h x +h^2\right)^{1/2}},
\]
\item the locally supported kernel
$L_{h,\lambda}:[-1,1] \rightarrow \R$ with $h \in (-1,1)$ and
$\lambda \in \mathbb{N}_0$ given by
\[
L_{h,\lambda}(x) :=
\left\{\begin{array}{l@{\quad \text{if} \quad}rcl}
0 & -1 &\le x \le& h, \\
\frac{\lambda+1}{2\pi(1-h)^{\lambda+1}}\left(x-h\right)^{\lambda} &
h & < x \le& 1,
\end{array}\right.
\]
or
\item the spherical Gaussian kernel
$G_{\sigma}:[-1,1] \rightarrow
\R$ with $\sigma>0$
\[
G_{\sigma}(x) := \e^{2\sigma x-2\sigma}\,.
\]
\end{enumerate}
For details see \cite{KeKuPo06}, all corresponding numerical examples can be
found in {\tt applications\ /fastsumS2}.

\subsection{Iterative reconstruction in magnetic resonance imaging}
%------------------------------------------------------------------------------
In magnetic resonance imaging (MRI) the raw data is measured in k-space, the
domain of spatial frequencies.
Methods that use a non-Cartesian sampling grid in k-space, e.g. a spiral, are
becoming increasingly important.
Reconstruction is usually performed by resampling the data onto a Cartesian
grid and the usage of the standard FFT - often denoted by gridding.
Another approach, the inverse model, is based on an implicit discretisation.
Both discretisations are solved efficiently by means of the NFFT and the
inverse NFFT, respectively.
Furthermore, a unified approach to field inhomogeneity correction has been
included, see \cite{KnKuPo,EgKnPo06} for details.
%------------------------------------------------------------------------------
\subsection{Computation of the polar FFT}
%------------------------------------------------------------------------------
The polar FFT is a special case of the NFFT, where one computes the Fourier
transform on particular grids.
Of course, the polar as well as a so-called pseudo-polar FFT can be computed
very accurately and efficiently by the NFFT.
Furthermore, the reconstruction of a $2d$ signal from its Fourier transform
samples on a (pseudo-)polar grid by means of the inverse nonequispaced FFT is
possible under certain density assumptions.
For details see \cite{FeKuPo06} and for further applications
\cite{AvCoDoElIs}.

%------------------------------------------------------------------------------
\subsection{Radon transform, computer tomography, and ridgelet transform}
%------------------------------------------------------------------------------
We are interested in efficient and high quality reconstructions of digital $N
\times N$ medical images from their Radon transform.
The standard reconstruction algorithm, the filtered backprojection, ensures a
good quality of the images at the expense of $\cO( N^3 )$ arithmetic
operations.
Fourier reconstruction methods reduce the number of arithmetic operations to
${\cal O}( N^2 \log N )$.
Unfortunately, the straightforward Fourier reconstruction algorithm suffers
from unacceptable artifacts so that it is useless in practice.
A better quality of the reconstructed images can be achieved by our algorithm
based on NFFTs.
For details see \cite{PoSt01IMA, PoSt00SPIE, PoSt02JFAA} and the directory
{\tt applications/radon}.
Another application of the discrete Radon transform is the discrete Ridgelet
transform, see e.g. \cite{CaDeDoYi}.
A simple test program for denoising an image by hard thresholding the ridgelet
coefficients can be found in {\tt applications/radon}.
It uses the NFFT-based discrete Radon transform and the translation-invariant
discrete Wavelet transform based on {\sc MatLab} toolbox WaveLab850
\cite{WaveLab}.
See \cite{FeMa05} for details.

\section{Introduction} \label{sect:1}
%===============================================================================
\setcounter{equation}{0}
NFFT~3 \cite{nfft3} is a C software library for computing
the nonequispaced fast Fourier transform (NFFT); see Appendix \ref{A.4} for
alternative denominations, further approaches, and references.
At the heart of the library is a fast algorithm that generalizes the
ubiquitous FFT \cite{CoTu65} from equally spaced to arbitrary sampling
points/spatial nodes, hence the name NFFT; see Appendix \ref{appendix.nfft}.
Our implementation is based on the popular FFTW library \cite{FFTW05}.
Unlike the FFT, the NFFT is not trivially inverted, which compells one to
resort to iterative techniques. Our library also implements these iterative
algorithms for inversion, as well as several other discrete transforms related to
or based on the NFFT. This paper is to present an overview over NFFT~3, the
underlying algorithmic concepts, and intents to serve as a general guideline.
We start in Section \ref{sect:nfft} with the definition of the nonequispaced
discrete Fourier transform (NDFT) as a generalization of the discrete
Fourier transform (DFT) to arbitrary nodes. The NFFT algorithm, its key properties,
and differences to the classical FFT are discussed.
Having settled the relevant definitions, the basic principles
of using the NFFT~3 software library are described in Section \ref{sect:lib}.
%shows how to compile and install the software package on
%your computer system.
%A small example in one dimension demonstrates the basic principles.
An overview over the software interface to the NFFT library routines concludes
this section.
In Section \ref{sect:gen}, several transforms that derive from the original NFFT
are described. This includes, among others, the NFFT on the unit sphere and
iterative schemes for inversion of the NFFT. Section \ref{sect:sum} is to summarize
the theoretical arithmetic costs of our algorithms and presents actual
performance measurements for our implementation.
In the final Section \ref{sect:exap}, a number of elementary numerical examples
as well as more advanced applications are given.
We have restricted ourselves to describe brief recipes which should be
sufficient for most users. For the experienced user, a comprehensive software
interface documentation is provided within the downloadable software package
\cite[doc/refman.pdf]{nfft3}.

\section{Nonequispaced discrete Fourier transform} \label{sect:nfft}
%===============================================================================
\setcounter{equation}{0}
Fast Fourier transforms (FFTs) have recently been generalized to
arbitrary sampling situations; see
\cite{duro93,bey95,AnDa96,st97,ware98,postta01} and the references in Appendix
\ref{A.4}.
A convenient approach is to define the discrete Fourier transform (DFT) as the
evaluation of a trigonometric polynomial, given by its Fourier coefficients,
at equispaced spatial nodes. This can then be generalized to arbitrary nodes.
\subsection{Discrete Fourier transform}
Following standard conventions \cite{loan,FFTW05} the (forward) discrete Fourier
transform (DFT) is defined as the calculation of the sums
\begin{equation} \label{eq.dft}
f_{j} = \sum_{k = 0}^{N-1} \hat{f}_{k} \mathrm{e}^{-2\pi\mathrm{i}jk/N} \qquad
(j=0,\ldots,N-1)
\end{equation}
for $N \in \mathbb{N}$ and given coefficients $\hat{f}_{k}\in\C$.
The transform is readily inverted, i.e.,
\begin{equation}
\label{eq.idft}
\hat{f}_{k} = \frac{1}{N} \sum_{j = 0}^{N-1} f_{j} \mathrm{e}^{2\pi\mathrm{i}kj/N}.
\end{equation}
Clearly, the computation of these transforms requires $\mathcal{O}(N^{2})$
arithmetic operations in general. Fast Fourier transforms (FFTs) are
$\mathcal{O}(N \log N)$ algorithms to compute the same result.
In matrix-vector notation, the DFT can be written as the matrix-vector product
\begin{align*}
\mathbf{f} = \mathbf{F} \, \mathbf{\hat{f}}, \quad
\mathbf{F} =
(\mathrm{e}^{-2\pi\mathrm{i}jk/N})_{j,k=0,\ldots,N}
\end{align*}
with vectors $\mathbf{f} = (f_j)_{j=0,\ldots,N-1}$,
$\mathbf{\hat{f}} = (\hat{f}_k)_{k=0,\ldots,N-1}$,
and the Fourier matrix $\mathbf{F}$.
%= (\mathrm{e}^{-2\pi\mathrm{i}jk/N})_{j,k=0,\ldots,N}$.
The inverse transform is equivalent to $\mathbf{\hat{f}} = \tfrac{1}{N}
\mathbf{F}^{\adj} \, \mathbf{f}$.
It is straightforward to generalize these concepts to multidimensional
transforms; see Section \ref{subsect.definition} below. But before we
define the NDFT, some notation is at order.
\subsection{Notation}
A $d$-dimensional nonequispaced discrete Fourier transform is defined by a set
of arbitrary spatial nodes $\mathcal{X}$ and a frequency bandwidth vector
$\mathbf{N}$.
Each node $\mathbf x_j$ in the sampling set
${\cal X}:=\{\mathbf{x}_j \in \T^d:\,j=0,\hdots,M-1\}$ is drawn from the
$d$-dimensional torus $\mathbb{T}^d \cong [-\tfrac{1}{2},\tfrac{1}{2})^d$
with the number of nodes equal to $|\mathcal{X}| = M$.
For each dimension $t = 0,\ldots,d-1$, the bandwidth $N_{t} \in 2\N$ is
defined as a fixed even number. These bandwidths are collected in the
vector $\mathbf{N} := \left({N_0},\ldots,N_{d-1}\right)^{\top}$.
Let us define the multi-index set
\begin{equation*}
I_{\mathbf{N}} :=
\mathbb{Z}^d \cap \prod_{t=0}^{d-1} \left[-\tfrac{N_t\rule[-0.4ex]{0ex}{1ex}}{2},
\tfrac{\rule[-0.4ex]{0ex}{1ex}N_t}{2}\right)
=\left\{ \mathbf{k}=\left(k_t\right)_{t=0,\hdots,d-1} \in
\Z^d: - \frac{N_t}{2} \le k_t < \frac{N_t}{2} ,\;t=0,\hdots,d-1\right\}.
\end{equation*}
Then the set $I_{\mathbf{N}}$ is a representation of all possible frequencies
in a transform. For simplicity, we use the convention that a multi-index
$\mathbf{k}$ can also reference elements in vectors or rows and columns of matrices
as if it were linearized to $k:=\sum_{t=0}^{d-1}
(k_t+\frac{N_t}{2}) \prod_{t'=t+1}^{d-1} N_{t'}$.
The inner product between a frequency index $\mathbf{k}$ and a node $\mathbf{x}$
is defined as usual, $\mathbf{k} \mathbf{x}:=k_0 x_0 +\hdots+
k_{d-1} x_{d-1}$.
Furthermore, we define the component-wise vector product $\mathbf{\sigma} \odot
\mathbf{N}:=\left(\sigma_0 N_0, \hdots, \sigma_{d-1} N_{d-1}, \right)^{\top}$,
and the reciprocal of a vector $\mathbf{N}$ with nonzero components, $\mathbf{N}^{-1}:=
\left({N_0}^{-1},\ldots,{N_{d-1}^{-1}}\right)^{\top}$.
The class of functions $f: \T^d \rightarrow \C$ that is naturally associated
with an index set $I_{\mathbf{N}}$ is the space of $d$-variate, one-periodic
trigonometric polynomials of degree at most $N_t$ along each dimension $t$,
$
T_{\mathbf{N}}:={\rm
span}\left(\eim{\mathbf{k}\,\mathbf{\cdot}\,}:\,\mathbf{k}
\in I_{\mathbf{N}}\right)
$.
This space has dimension $\dim T_{\mathbf{N}} = |I_{\mathbf{N}}| = N_{0} \cdot
\ldots \cdot N_{d-1}$.
%-------------------------------------------------------------------------------
\subsection{Definition}
\label{subsect.definition}
%-------------------------------------------------------------------------------
We are now ready to define the \emph{nonequispaced discrete Fourier transform (NDFT)}
as a generalization of the forward DFT \eqref{eq.dft} to arbitrary nodes.
Given Fourier coefficients $\hat f_{\mathbf{k}} \in \C$,
$\mathbf{k}\in I_{\mathbf{N}}$, as input, the NDFT is defined as the evaluation
of the corresponding trigonometric polynomial $f \in T_{\mathbf{N}}$ at the
set of $M$ arbitrary nodes $\mathcal{X}$, i.e., the calculation of the sums
\begin{equation}
\label{eq:nfft}
f_j = \sum_{\mathbf{k}\in I_{\mathbf{N}}} \hat{f}_{\mathbf{k}}
\eim{\mathbf{k}\mathbf{x}_j} \qquad (j=0,\hdots,M-1).
\end{equation}
To see how this compares with the definition of the DFT, take
$\mathbf{N}=(N,\hdots,N)^{\top}$, $N\in 2\N$, and $N^d$
equispaced nodes $\mathbf{x}_{\mathbf{j}}={\frac{1}{N}}\mathbf{j}$,
$\mathbf{j} \in I_{\mathbf{N}}$. Then \eqref{eq:nfft}
reduces (up to an index shift) to a usual multidimensional forward
DFT.
The NDFT \eqref{eq:nfft} too can be written as a matrix-vector product,
\begin{equation*}
\mathbf{f} = \mathbf{A} \mathbf{\hat{f}},
\end{equation*}
with the vectors $\mathbf{f} := \left(f_j\right)_{j=0,\hdots,M-1}$,
$\mathbf{\hat{f}} :=(\hat{f}_{\mathbf{k}})_{\mathbf{k}\in
I_{\mathbf{N}}}$, and the nonequispaced Fourier matrix $\mathbf{A}
:= \left(\eim{\mathbf{k}\mathbf{x}_j}\right)_{j=0,\hdots,M-1;\;\mathbf{k}\in
I_{\mathbf{N}}}$.
Typically, the matrix $\mathbf{A}$ is not square. Even if this should be the case,
it is usually neither orthogonal nor has an inverse. Therefore,
the definition of an inverse NDFT transform is not canonical.
Instead, it is customary to define the \emph{adjoint NDFT} by
the matrix-vector product
\[
\mathbf{\hat{h}} = \mathbf{A}^{\adj} \mathbf{f}.
\]
This is equivalent to the sums
\begin{equation}
\label{eq:nfftH}
\hat{h}_{\mathbf{k}} = \sum_{j=0}^{M-1} \hat{f}_{ j} \eip{\mathbf{k}
\mathbf{x}_j} \qquad (\mathbf{k}\in I_{\mathbf{N}}).
\end{equation}
The NFFT algorithm, implemented in our library, is a fast approximate algorithm
to compute the sums in \eqref{eq:nfft}. It contains also a fast algorithm to
compute the adjoint transform \eqref{eq:nfftH}.
%-------------------------------------------------------------------------------
\subsection{Key features}
%-------------------------------------------------------------------------------
A $d$-dimensional DFT of degree $N$ along each dimension has $N^d$
input and output coefficients. This generally requires $\mathcal{O}(N^{d+1})$
to compute the transform. FFTs reduce this to $\mathcal{O}(N^{d} \log N)$.
The cost for nonequispaced fast transforms is similar. However, it is important
to note that there the number of nodes as well as their configuration are arbitrary.
This generally implies $M \neq |I_{\mathbf{N}}|$.
The direct calculation of the sums in \eqref{eq:nfft}, an algorithm which we
also denote NDFT, requires $\cO(M |I_{\mathbf{N}}|)$ floating point operations.
%and uses no additional scratch memory.
Since the number of nodes $M$ is typically of order $|I_{\mathbf{N}}|$, this cost
is considered too expensive for most applications.
The NFFT~3 library implements a fast approximate algorithm, called
NFFT, which computes the same result using only
${\cal O}\left(|I_{\mathbf{N}}| \log |I_{\mathbf{N}}| + |\log \varepsilon|^d
M\right)$ operations.
Here, $\varepsilon$ is the desired accuracy of the computation. The
constant contained in this notation depends on the amount of extra
memory spent for precomputation; see Appendix \ref{sect:windows}.
Let us briefly compare NDFT/NFFT and classical DFT/FFT to observe some
key features and differences:
While a multidimensional DFT/FFT is uniquely defined by the bandwidth
vector $\mathbf{N}$ alone, i.e., the sampling set $\mathcal{X}$ is fixed,
the NDFT/NFFT also depend on the actual choice of $\mathcal{X}$;
see Subsection \ref{subsect.definition}.
FFT algorithms are usually exact algorithms with small errors in the result
caused only by limitations of floating point arithmetic.
The NFFT algorithm purposely introduces a systematic error in the computation
to achieve its favorable arithmetic cost.
This additional error can be controlled, and, if deemed necessary, can be
reduced to the order of machine precision.
To this end, the NFFT uses an \emph{oversampled} FFT internally (in our case
we use routines from FFTW) together with a pre- and post-processing step.
%While the pre-processing step is exact, the post-processing step contains a
%\emph{truncated} approximation scheme.
This introduces two additional parameters,
an \emph{oversampling factor} and a \emph{truncation parameter}, that
control the accuracy of the NFFT. More details are found in Appendix
\ref{appendix.nfft}.
%\textbf{Dem ersten Referee folgend, koennten hier mehr Details zum Algorithmus
%stehen, insbesondere welche zusaetzlichen Parameter der Benutzer jetzt
%einstellen kann. Gut waeren sicher Verweise auf Stellen weiter hinten, die auf
%einzelne Punkte genauer eingehen. Ich denke, eine gute Erklaerung der
%zusaetzlichen Freiheitsgrade und Parameter ist sehr wichtig fuer das
%Verstaendnis.}
%For now, it suffices to note that the NFFT algorithm has a similar complexity
%than the classical FFT algorithm but that it is an approximate algorithm whose
%accuracy is controlled by the user.
%===============================================================================
\section{Guidelines for using the library} \label{sect:lib}
%===============================================================================
NFFT~3 is a free software library completely written in C.
The downloadable source code comes as a GNU-style package and follows standard
conventions. Brief installation instructions and a source tree can be found in
Appendix \ref{sect:inst}.
To compile and link programmes that use NFFT~3, you also need the FFTW library
\cite{fftw} in version 3.0.0 or better.
%-------------------------------------------------------------------------------
\subsection{Interface} \label{sect:general_proc}
%-------------------------------------------------------------------------------
The interface of NFFT~3 resembles that of FFTW 3. A transform is
specified by creating a \emph{plan} -- a data structure that contains the
information to determine the characteristics of a transform. In contrast to
FFTW 3, it is also necessary to call a precomputation routine, once the
nodes $\cal X$ have been provided. After these initial steps, transforms are
executed on input data by invoking an execution routine.
At the end of its lifetime, a plan is finalized and all associated data
structures are destroyed.
%-------------------------------------------------------------------------------
\subsection{Typical workflow} \label{sect:general_ex}
%-------------------------------------------------------------------------------
This brief example is to illustrate the basic principles. It shows how to
compute a one-dimensional NFFT.
%-------------------------------------------------------------------------------
\subsubsection*{Creating a plan}
%-------------------------------------------------------------------------------
An NFFT plan \verb"p" is declared by
\begin{verbatim}
nfft_plan p;
\end{verbatim}
The simplest way to initialize the plan for a one-dimensional transform is to
call
\begin{verbatim}
nfft_init_1d(&p,N0,M);
\end{verbatim}
The arguments to \verb"nfft_init_1d" are the pointer \verb"&p" to the yet
uninitialized plan, the number of Fourier
coefficients \verb"N0", and the number of nodes \verb"M".
This creates and initializes all data structures inside the
plan. Memory for Fourier coefficients, nodes, and
function values is allocated automatically.
%But to completely specify the transform, we also have to provide the
%nodes.
%-------------------------------------------------------------------------------
\subsubsection*{Providing the nodes}
%-------------------------------------------------------------------------------
The nodes have to be stored in the member array \verb"p.x".
In one dimension, the coordinate of the $j$th node is a number in
$[-\tfrac{1}{2},\tfrac{1}{2})$ that is stored at the index $j$, i.e.,\\[2ex]
%\begin{verbatim}
\verb" p.x[j] = "\textsl{your choice in [-0.5,0.5)}\verb";"
%\end{verbatim}
%-------------------------------------------------------------------------------
\subsubsection*{Precomputation}
%-------------------------------------------------------------------------------
The precomputation procedure for the plan is invoked (conditionally) by
\begin{verbatim}
if (p.nfft_flags & PRE_ONE_PSI)
nfft_precompute_one_psi(&p);
\end{verbatim}
NFFT~3 uses different strategies here which are free of choice by the user via
passing the appropriate flag to one of the more advanced plan initialization
routines. A default strategy is chosen by the simple initialization routines.
For convenience, the flag \verb+PRE_ONE_PSI+ indicates that precomputation
is necessary; see Appendix \ref{sect:windows} for details.
%-------------------------------------------------------------------------------
\subsubsection*{Providing the Fourier coefficients}
%-------------------------------------------------------------------------------
Fourier coefficients are stored in the one-dimensional member array
\verb"p.f_hat". In the one-dimensional case this array contains the Fourier
coefficients in the order $\hat{f}_{-N/2},\hdots,\hat{f}_{N/2-1}$.
They are accessed by\\[2ex]
%\begin{verbatim}
\verb" p.f_hat[k] = "\textsl{your choice in the complex numbers}\verb";"
%\end{verbatim}
%-------------------------------------------------------------------------------
\subsubsection*{Execution}
%-------------------------------------------------------------------------------
To compute \eqref{eq:nfft} with the NFFT algorithm, invoke
\begin{verbatim}
nfft_trafo(&p);
\end{verbatim}
The $M$ output values $f_j$ are stored in the one-dimensional member array
\verb"p.f". To compute a second NFFT with different input data, simply
update the Fourier coefficients in \verb"p.f_hat" and invoke \verb"nfft_trafo"
a second time.
The adjoint transform \eqref{eq:nfftH} is computed by \verb+nfft_adjoint+. Here,
the input is put in \verb"p.f" and the output is written to \verb"p.f_hat".
%-------------------------------------------------------------------------------
\subsubsection*{Finalization}
%-------------------------------------------------------------------------------
Since the initialization routine for the plan has allocated memory, it is
essential to finalize the plan, once it is no longer
needed. This is done by
\begin{verbatim}
nfft_finalize(&p);
\end{verbatim}
%-------------------------------------------------------------------------------
\subsubsection*{Example}
%-------------------------------------------------------------------------------
Here is a brief example that computes a one-dimensional NFFT with 14
Fourier coefficients and 19 nodes. The routine is part of the example program
\verb"simple_test.c" which is found under \verb"examples/nfft/" in the
software package. It uses some auxilliary routines from the NFFT~3 header
\verb"util.h" to initialize vectors with random entries and to write them
to the standard output.
\begin{verbatim}

\subsection{Multivariate transforms}
%-------------------------------------------------------------------------------
In $d$ dimensions, the nodes $\mathbf{x}_j$ in the sampling set
$\mathcal{X}$, as well as the frequency indices $\mathbf{k}$ in the set
$I_{\mathbf{N}}$ are $d$-dimensional vectors. This affects the storage layout of
the arrays \verb"x" and \verb"f_hat". Generally, both remain
one-dimensional and all $d$-dimensional quantities are linearized.
For \verb"x" this means that the $t$th coordinate of the $j$th node
($t=0,\ldots,d-1$; $j = 0,\ldots,M-1$) is defined via\\[\parskip]
\noindent\verb" p.x[d*j+t] = "\textsl{your choice in [-0.5,0.5)}\verb";"\\[\parskip]
\noindent This linear ordering has been chosen because the node configuration
may be completely unstructured.
Analogously, the Fourier coefficient $\hat{f}_{\mathbf{k}}$ is stored in
\verb"f_hat[k]" at the linearized index \verb"k"$ = \sum_{t=0}^{d-1}
(k_t+\frac{N_t}{2}) \prod_{t'=t+1}^{d-1} N_{t'}$.
Due to software engineering considerations, we do not offer alternative data
layouts, even if the nodes belong to a multidimensional structure, e.g. a
tensor product grid. Moreover, NFFT~3 does currently not offer support for strided
data or even more general FFTW-style i/o-tensors.
%-------------------------------------------------------------------------------
\subsection{Programming interface and data structures}
%-------------------------------------------------------------------------------
The programming interface for the NFFT module is summarized in
Table \ref{table:nfft_user_fun}. To allow for a comparison with the NDFT algorithm,
the routine \verb"ndft_trafo" computes the transform via direct
evaluation of \eqref{eq:nfft}. The routines \verb"ndft_adjoint"
and \verb"nfft_adjoint" compute adjoint transforms \eqref{eq:nfftH},
respectively. The Initialization routines \verb"nfft_init_1d",
\verb"nfft_init_2d", \verb"nfft_init_3d" allow for convenient initialization
of plans for one-, two-, and three-dimensional transforms with default
parameters. Plans for general multivariate transforms are created using
\verb"nfft_init". For the experienced user, the function \verb"nfft_init_guru"
allows control over all relevant parameters.
The most important members of the \verb"nfft_plan" data type are listed in Table
\ref{table:nfft_members}. Only \verb"f_hat", \verb"f", and
\verb"x" are to be modified by the user.

\section{Generalizations} \label{sect:gen}
%===============================================================================
This section surveys further generalizations of the NFFT algorithm that are
implemented by the NFFT~3 library. The interfaces resemble that of the NFFT
module described above, with the prefix \verb+nfft_+ replaced by the
acronym related to the specific transform in all names. Details can be found in
the API documentation accompanying the library. All algorithms, with exception of
the discrete polynomial transform, are based on the same computational procedure
as the NFFT.
%-------------------------------------------------------------------------------
\subsection{NFST/NFCT - Nonequispaced fast sine/cosine transforms}
%-------------------------------------------------------------------------------
Discrete (co)sine transforms (DCT/DST) are closely related real variants of the
discrete Fourier transform DFT. In the same way, nonequispaced discrete (co)sine
transforms (NDCT/NDST) are real transforms related to the NDFT. They are
parameterised by arbitrary nodes $\mathbf{x}_j \in [0,\frac{1}{2}]^d$.
Frequencies $\mathbf{k}$ are taken from one of the index sets
\begin{align*}
I_{\mathbf{N}}^C &:= \left\{ \mathbf{k}=\left(k_t\right)_{t=0,\hdots,d-1}
\in \Z^d: 0 \le k_t < N_t ,\;t=0,\hdots,d-1\right\}, \\
I_{\mathbf{N}}^S &:= \left\{ \mathbf{k}=\left(k_t\right)_{t=0,\hdots,d-1} \in
\Z^d: 1 \le k_t < N_t ,\;t=0,\hdots,d-1\right\},
\end{align*}
where $I_{\mathbf{N}}^C$ corresponds to the NDCT and $I_{\mathbf{N}}^S$ to the
NDST, respectively. For given real Fourier coefficients
$\hat f_{\mathbf{k}} \in \R$, NDCT and NDST are defined by
\begin{equation*}
f_j = \sum_{\mathbf{k}\in I_{\mathbf{N}}^C}
\hat{f}_{\mathbf{k}}
\cos(2\pi(\mathbf{k}\odot\mathbf{x}_j))\quad
(j=0,\hdots,M-1),
\qquad
f_j = \sum_{\mathbf{k}\in I_{\mathbf{N}}^S}
\hat{f}_{\mathbf{k}}
\sin(2\pi(\mathbf{k}\odot\mathbf{x}_j)),
\end{equation*}
respectively. Here, for notational convenience, we have defined
$\cos(\mathbf{x}) := \cos(x_0) \cdot \hdots \cdot \cos(x_{d-1})$ and
$\sin(\mathbf{x}) := \sin(x_0) \cdot \hdots \cdot \sin(x_{d-1})$.
Straightforward algorithms for these transforms need $\cO(M
|I_{\mathbf{N}}^C|)$ and $\cO(M |I_{\mathbf{N}}^S|)$ arithmetic operations.
The fast algorithms (NFST/NFCT) need $\cO(|I_{\mathbf{N}}^S| \log
|I_{\mathbf{N}}^S| + |\log \varepsilon|^d M)$ and $\cO(|I_{\mathbf{N}}^C| \log
|I_{\mathbf{N}}^C| + |\log \varepsilon|^d M)$ operations, respectively.
Note that for these real transforms, the adjoint variants coincide with the
transposed versions. Details about the implemented algorithms can be found in
\cite{tili00,po01,fepo02}.
%-------------------------------------------------------------------------------
\subsection{NSFFT - Nonequispaced sparse fast Fourier transform}
%-------------------------------------------------------------------------------
In higher dimensions, the so-called ``curse of dimensionality''
\cite{Zeng91,Spr00,BuZe04} often requires the use of Fourier series where
frequency indices are restricted to the hyperbolic cross
\begin{equation*}
H_N^d := \bigcup_{\mathbf{N}\in\N^d,\, |I_{\mathbf{N}}| = N} I_{\mathbf{N}},
\qquad N=2^{J+2},\;J\in\NZ,
\end{equation*}
which has only $\cO(N \log^{d-1} N)$ degrees of freedom compared to
$\cO(N^d)$ in the plain case. If compared to ordinary Fourier series,
the approximation error commited, which is typically measured in a norm of
dominated mixed smoothness, can be shown to get worse by a factor of only
$\log^{d-1} N$ (see \cite{Spr00}).
The \emph{nonequispaced sparse discrete Fourier transform (NSDFT)} is defined as
the evaluation of
\begin{equation*}
f_j = \sum_{\mathbf{k}\in H_N^d}
\hat f_{\mathbf{k}} \eim{\mathbf{k} \mathbf{x}_j} \qquad (j=0,\ldots,M-1)
\end{equation*}
with given nodes $\mathbf{x}_j\in \T^d$ and Fourier coefficients
$\hat f_{\mathbf{k}}\in\C$. The algorithms implemented in NFFT~3 reduce the
number of arithmetic operations from $\cO(M N\log^{d-1}N)$ to
$\cO(N\log^2 N+|\log \varepsilon|^2 M)$ in two dimensions ($d = 2$), and to
$\cO(N^{3/2} \log N+ |\log \varepsilon|^3 M)$ in three dimensions ($d = 3$).
Details are found in \cite{FeKuPo} for details.
%-------------------------------------------------------------------------------
\subsection{NNFFT - fast Fourier
transform for nonequispaced data in space and frequency domain}
%-------------------------------------------------------------------------------
The NNFFT is a variant of the NFFT where also frequencies are no
longer equispaced integer multi-indices.
The transform is defined by
\begin{equation*}
f_j = \sum_{l=0}^{L-1} \hat f_l \eim{\left(\mathbf{v}_l \odot
\mathbf{N}\right)\mathbf{x}_j} \qquad (j =0,\hdots,M-1)
\end{equation*}
with Fourier coefficients $\hat{f}_l \in\C$, and arbitrary frequencies
$\mathbf{v}_l \in \T^d$ and nodes $\mathbf{x}_j \in \T^d$.
Here, $\mathbf{N}\in \N^d$ is called the \emph{nonharmonic
bandwidth}. This transform is known as \textit{fast Fourier
transform for nonequispaced data in space and frequency domain (NNFFT)}
\cite{duro93,elst,postta01} or as \emph{type 3 nonuniform FFT} \cite{LeGr05}
and takes $\cO(|I_{\mathbf{N}}|\log|I_{\mathbf{N}}| + |\log
\varepsilon|^d(L+M))$ arithmetic operations to compute.
%------------------------------------------------------------------------------
\subsection{NFSFT - nonequispaced fast spherical Fourier transform}
\label{sect:gen:nfsft}
%------------------------------------------------------------------------------
Denote by $\S^2:= \big\{\mathbf{x} \in \R^{3}:\;\|\mathbf{x}\|_2=
1\big\}$ the two-dimensional unit sphere.
In spherical cordinates, any point on $\S^2$ is identified with a pair of
angles $(\vartheta,\varphi)^{\top}\in [0,\pi]\times [0,2\pi)$.
Hence, a sampling set on the sphere can be defined by
$
\mathcal{X}: = \left\{\left(\vartheta_{j},\varphi_{j}\right)
%\in \mathbb{S}^2
:\,j=0,\hdots,M-1\right\}.
$
A convenient basis of orthogonal functions on $\S^2$ are spherical harmonics
$Y_k^n : \S^2 \rightarrow \C$, $k \in \mathbb{N}_{0}$, $|n| \le k$,
defined by
\begin{equation*}
Y_k^n(\vartheta,\varphi) := P_k^{|n|}(\cos\vartheta)
\, \mathrm{e}^{\mathrm{i} n \varphi}.
\end{equation*}
Here, $P_k^{|n|}$ are the associated Legendre
functions of degree $k$ and order $|n|$ (see \cite[pp. 331]{abst}).
Frequencies for a finite transform up to bandwidth $N$ are collected in the
index set
\[
J_{N} := \{(k,n)\in\Z^2:\,k=0,\ldots,N;\; n=-k,\ldots,k\}.
\]
The \emph{nonequispaced discrete spherical Fourier transform (NDSFT)} is
defined as the calculation of
\begin{equation*}
f_j = \sum_{(k,n) \in \, J_{N}} \hat{f}_k^n \,
Y_k^n\left(\vartheta_{j},\varphi_{j}\right) \qquad (j=0,\ldots,M-1).
\end{equation*}
The direct method (NDSFT) clearly needs $\cO(M N^2)$ arithmetic operations.
The approximate $\cO(N^2 \log^2 N + |\log{\varepsilon}|^2M)$ algorithm
implemented in the NFFT~3 library (\emph{NFSFT}) is a combination of the
fast polynomial transform (FPT; see next subsection) and the NFFT.
%, and are given in Algorithms \ref{alg:NFSFT} and
%\ref{alg:adjointNFSFT}.
It was introduced in \cite{kupo02} while the adjoint variant was
developed in \cite{KePo06}. Other algorithms, mostly for particular
sampling sets, exist (e.g. \cite{drhe,SuTa01,roty}).

%\end{algorithm}
%-------------------------------------------------------------------------------
\subsection{FPT - fast polynomial transform} \label{sect:fpt}
%-------------------------------------------------------------------------------
A \emph{discrete polynomial transform} (DPT) is a generalization of the DFT
from complex exponentials $\mathrm{e}^{\mathrm{i} k x}$ to
systems of algebraic polynomials that satisfy a three-term recurrence;
see \cite[pp. 773]{abst}.
More precisely, let $p_{0},p_{1},\hdots:[-1,1]\rightarrow\R$ be a sequence of
polynomials satisfying the recurrence
\begin{align}
\label{eq.threeterm}
p_{k+1}(x) & = (\alpha_{k} x + \beta_{k})p_{k}(x) + \gamma_{k} p_{k-1}(x) &
(k \ge 0),
\end{align}
where $p_{-1}(x) := 0$, $p_{0}(x) := 1$, and $\alpha_{k} \neq 0$, $k\ge 0$.
Then every $p_{k}$ is a degree-$k$ polynomial. Typical examples are the
Legendre polynomials $P_k(x)$ or the Chebyshev polynomials of first
kind $T_{k}(x) := \cos(k \arccos x)$. Let a finite linear expansion of the form
\begin{equation*}
f(x) = \sum_{k=0}^{N} a_{k} p_{k}(x)
\end{equation*}
be given. The DPT in our sense is defined as the
computation of the coefficients $b_{k}$ in the expansion
\[
f(x) = \sum_{k=0}^N b_{k} T_{k}(x).
\]
Implemented directly, this computation takes $\cO(N^2)$ arithmetic operations.
The \emph{fast polynomial transform (FPT)} is an $\cO(N \log^2 N)$
algorithm to compute the same result. It is implemented in the
NFFT~3 library following the approach in \cite{postta98}. This is based on using
the three-term-recurrence relation \eqref{eq.threeterm} repeatedly, together
with a fast method for polynomial multiplication in the Chebyshev
basis, and a cascade-like summation process. More details can be found in
\cite{drhe,drhero,postta98,po01} and references therein.
%------------------------------------------------------------------------------
\subsection{Inversion and solver module} \label{sect:general_proc_infft}
%------------------------------------------------------------------------------
The NDFT differs from the DFT also in that an inversion formula similar to
\eqref{eq.idft} generally does not exist; see Section \ref{subsect.definition}.
A more general view is at order to define what should be an inverse NDFT/NFFT
transform. This section is devoted to explain our approach for the NFFT. But
everything also applies to the mentioned NFFT variants.
Inversion of the NDFT means the computation of Fourier coefficients
$\hat{f}_{\mathbf{k}}$, $\mathbf{k} \in I_{\mathbf{N}}$, from given function
samples $y_{j}$ at nodes $\mathbf{x}_j$, $j = 0,\ldots,M-1$.
In matrix-vector notation, this is equivalent to solving the linear system
\begin{equation}\label{eq:infft}
\mathbf{A} \mathbf{\hat{f}} \approx \mathbf{y}.
\end{equation}
%for the vector $\mathbf{\hat{f}}\in\C^{|I_{\mathbf{N}}|}$.
This can be either and overdetermined system if $|I_{\mathbf{N}}| \le
M$ (this includes the quadratic case) or an underdetermined system
if $|I_{\mathbf{N}}| > M$.
Generally, this compels us to look for a pseudo-inverse solution
$\mathbf{\hat{f}}^{\dagger}$ (see e.g. \cite[p. 15]{Bj96}).
For this, we also require that the nonequispaced Fourier matrix $\mathbf{A}$
have full rank. Eigenvalue estimates in \cite{FeGrSt95,BaGr03,KuPo04} indeed assert that this
condition is satisfied if the sampling set $\cal X$ is uniformly dense or uniformly
separated with respect to the inverse bandwidth $\mathbf{N}^{-1}$.
For the overdetermined case, we now consider a weighted least squares problem,
while for the consistent underdetermined case, we look for a solution of an
interpolation problem. Both can be solved by iterative algorithms using
NFFT and adjoint NFFT to realize fast matrix-vector multiplications
involving $\mathbf{A}$ and $\mathbf{A}^{\adj}$, respectively.
%-------------------------------------------------------------------------------
\subsubsection*{Weighted least squares problem}
%-------------------------------------------------------------------------------
If $|I_{\mathbf{N}}|\le M$, the linear system \eqref{eq:infft} is overdetermined
which typically implies that the given data $y_j\in \C,\;j=0,\hdots,M-1,$ can
only be approximated up to a residual $\mathbf{r}:=\mathbf{y}-\mathbf{A}
\mathbf{\hat{f}}$. Therefore, we consider the \emph{weighted least squares problem}
\begin{equation*}
\sum_{j=0}^{M-1} w_j |y_j-f(x_j)|^2
\stackrel{\mathbf{\hat{f}}}{\rightarrow} \min
\end{equation*}
with weights $w_j> 0$, $\mathbf{W}:=\diag(w_j)_{j=0,\hdots,M-1}$. This weights
might be used to compensate for clusters in the sampling set ${\cal X}$.
The weighted least squares problem is equivalent to solving
the \emph{weighted normal equation of first kind},
$
\mathbf{A}^{\adj} \mathbf{W} \mathbf{A} \mathbf{\hat{f}} = \mathbf{A}^{\adj}
\mathbf{W} \mathbf{y}.
$
This can be done, e.g., by using the Landweber (or Richardson) iteration,
the steepest descent method, or the conjugate gradient method for least
squares problems. The latter method is given in pseudo-code in Algorithm
\ref{algo:wCGNR(E)} (left). The NFFT~3 library nevertheless implements
all three algorithms.

\end{algorithm}
%-------------------------------------------------------------------------------
\subsubsection*{Interpolation problem}
%-------------------------------------------------------------------------------
If $|I_{\mathbf{N}}|>M$, and if the linear system \eqref{eq:infft} is
consistent, the data $y_j\in \C,\;j=0,\hdots,M-1,$ can be interpolated exactly.
But since there exist multiple solutions, we consider the
\emph{constrained minimization problem}
\begin{equation*}
\label{eq:ip}
\sum_{\mathbf{k}\in I_{\mathbf{N}}} \frac{|\hat f_{\mathbf{k}}|^2}{\hat
w_{\mathbf{k}}} \stackrel{\mathbf{\hat{f}}}{\rightarrow} \min \quad
\text{subject to} \quad \mathbf{A} \mathbf{\hat{f}} = \mathbf{y},
\end{equation*}
which incorporates ``damping factors'' $\hat w_{\mathbf{k}}> 0$,
$\mathbf{\hat{W}}:= \diag(\hat w_{\mathbf{k}})_{\mathbf{k}\in
I_{\mathbf{N}}}$. A smooth solution, i.e., a solution with rapid decay of
Fourier coefficients $\hat{f}_{\mathbf{k}}$, is favored if the damping
factors $\hat{w}_{\mathbf{k}}$ are decreasing themselves.
The interpolation problem is equivalent to the
\emph{damped normal equation of second kind}
$
\mathbf{A} \mathbf{\hat{W}} \mathbf{A}^{\adj} \mathbf{\tilde{f}}
= \mathbf{y}
$,
$\mathbf{\hat{f}} =
\mathbf{\hat{W}} \mathbf{A}^{\adj} \mathbf{\tilde{f}}
$.
The conjugate gradient method applied to this linear system is given in
Algorithm \ref{algo:wCGNR(E)} (right). Of course, the NFFT~3 library also
implements this scheme.

\section{Summary and performance analysis}\label{sect:sum}
%==============================================================================
This section is to provide a performance analysis of the NFFT algorithm.
The asymptotic bounds on the number of floating point operations for the
nonequispaced fast Fourier transform (NFFT) and its variant on the sphere

The rest of the section is to provide results of actual performance
measurements for our implementation of the NFFT in spatial
dimensions $d=1,2,3$. Computation time measurements and a numerical
confirmation of the error estimates for the window functions
(\ref{gaussian}-\ref{kaiser}) with respect to the so-called cut-off
parameter are given.
For our tests, we used a computer system with an AMD
$\text{Athlon}^{\text{\texttrademark}}$ XP 2700+ processor, 1GB memory,
SuSE Linux with kernel 2.4.20-4GB-athlon, and the GCC 3.3 compiler.
All computations were carried out in double precision using the compiler
option \verb"-O3". For all tests with random input, the nodes
$\mathbf{x}_j$ and the Fourier coefficients $\hat f_{\mathbf{k}}$ were
drawn from a uniform pseudo-random distribution in the respective domains,
i.e., $\mathbf{x}_j \in \mathbb{T}^d$ and
$\hat f_{\mathbf{k}} \in [0,1] \times [0,1]{\rm i}$. The code for these
and more examples and applications can be found in the directories
\verb"examples/" and \verb"applications/" of the NFFT~3 package.
%------------------------------------------------------------------------------
\subsection{Computation time with respect to problem size}
%------------------------------------------------------------------------------
We compared computation times for ordinary FFTs (using FFTW
3.0.0 \cite{FFTW05,fftw} in double precision with the flag
\texttt{FFTW\_MEASURE}),
direct nonequispaced discrete Fourier transforms (NDFTs), and nonequispaced fast
Fourier transforms (NFFTs) for different problem sizes
$|I_{\mathbf{N}}|$ in dimensions $d=1,2,3$.
The multibandwidth $\mathbf{N}$ was chosen to
$\mathbf{N}=(N,\hdots,N)^{\top},\;N\in 2\N$.
The nodes for FFTs are fixed and restricted to the lattice $\mathbf{N}^{-1}\odot
I_{\mathbf{N}}$.
For NDFTs and NFFTs, we chose $M = N^d$ random nodes and used an oversampling
factor $\sigma=2$, cut-off parameters $m = 2$ and $m = 4$, and the
Kaiser-Bessel window function (precomputation flags \verb"PRE_PSI" and
\verb"PRE_PHI_HUT").
With these options, the accuracy measured by
\begin{equation}\label{Einf}
E_{\infty}:={\max_{0\le
j0$,
our algorithm requires $\cO(L+M)$ arithmetic operations instead of
$\mathcal{O}(LM)$ via direct calculation.
For singular kernels $K$, e.g.
\begin{equation*}
\frac{1}{x^2},\; \frac{1}{|x|}, \; \log |x|, \;
x^2 \log |x|, \; \frac{1}{x}, \;
\frac{\sin(c x)}{x},\; \frac{\cos(c x)}{x}, \; \cot(cx)
\end{equation*}
it is imperative to apply an additional regularization procedure. The cost then
becomes $\cO(L \log L +M)$ or $\cO(M\log M + L)$ provided that
either the source nodes $\mathbf{x}_l$ or the target nodes $\mathbf{y}_j$ are
uniformly distributed to a reasonable degree.
This fast method, which was proposed in \cite{post02,postni04,FeSt03},
generalizes the diagonalization of convolution matrices by Fourier matrices to
settings with arbitrary nodes.
Also, our method yields nearly the same cost as the FMM \cite{beatgreen97}
while allowing for an easy exchange of the kernel $K$.
A recent application in particle simulation is given in \cite{popori05}.
The directory \texttt{applications/fastsum} contains C and {\sc MatLab} programs
showing how to use the fast summation method.
%-------------------------------------------------------------------------------
%\subsection{Fast Gauss transform}
%-------------------------------------------------------------------------------
As a special case, let us consider the fast Gauss transform. This is the calculation of sums of the form
\begin{align*}
g\left(y_j\right) & :=\sum_{l=0}^{L-1} \alpha_l {\rm e}^{-\sigma|y_j-x_l|^2} &
(j=0,\ldots,M-1)
\end{align*}
for source and target nodes $x_l,y_{j}\in[-\frac{1}{4},\frac{1}{4}]$,
complex coefficients $\alpha_l \in \C$, and a complex parameter
$\sigma =a +{\rm i} b$, $a>0$, $b\in\R$ with $\mathcal{O}(L + M)$ operations.
For details see \cite{AnBe04,KuPoSt06}.
Numerical examples found in \cite{KuPoSt06} can be reproduced with the programs
found in the directory \texttt{applications/fastgauss}.
%-------------------------------------------------------------------------------
%\subsection{Summation of zonal functions on the sphere}
%-------------------------------------------------------------------------------
On the sphere $\mathbb{S}^2$, the equivalent of radial functions are \emph{zonal
functions}. Fast summation of zonal functions on the sphere is the computation
of
sums of the form
\begin{equation*}
g\left(\mathbf{\xi}_j\right) := \sum_{l = 0}^{L-1} \alpha_l K\left(\mathbf{\eta}_l
\cdot \mathbf{\xi}_j\right) \qquad (j=0,\ldots,M-1)
\end{equation*}
for source and target nodes $\mathbf{\eta}_l,\mathbf{\xi}_j \in \S^2$, and real
coefficients $\alpha_l \in \R$ with $\cO(L+M)$ operations.
Our algorithm is based on the nonequispaced fast spherical Fourier
transform. It and can be easily adapted to different kernels $K$, e.g. the
Poisson kernel, smooth locally supported kernels, or the spherical Gaussian
kernel. For details see \cite{KeKuPo06}. Numerical examples
are found under \verb+applications/fastsumS2/+.
%-------------------------------------------------------------------------------
\subsection{Applications in medical imaging}
%-------------------------------------------------------------------------------
%-------------------------------------------------------------------------------
%\subsection{Iterative reconstruction in magnetic resonance imaging}
%-------------------------------------------------------------------------------
In magnetic resonance imaging (MRI), raw data is measured in \emph{k-space}, the
domain of spatial frequencies. Methods that use non-Cartesian sampling grids
in k-space, e.g. a spiral, have received increasing attention recently.
Reconstruction is usually done by resampling the data onto a Cartesian
grid to use the standard FFT. This is often called \emph{gridding}.
A so-called inverse model is based on an implicit discretization and both
methods can be implemented efficiently using the NFFT and the inverse NFFT,
respectively (see \cite{KnKuPo} and references therein).
Furthermore, approaches to field inhomogeneity correction have been proposed
in \cite{SuNoFe03,EgKnPo06}.
Numerical tests are found in \verb+applications/mri/+.
%-------------------------------------------------------------------------------
%\subsection{Radon transform, computer tomography, and ridgelet transform}
%-------------------------------------------------------------------------------
In computerized tomography (CT) an $N \times N$ (medical) image is to be
reconstructed from its Radon transform.
The standard reconstruction algorithm, the filtered backprojection, yields
reasonably good images at the expense of $\cO( N^3 )$ arithmetic operations.
Fourier reconstruction methods reduce the number of arithmetic operations to
${\cal O}( N^2 \log N )$.
Unfortunately, straightforward Fourier reconstruction algorithms suffer
from unacceptable artifacts making them useless in practice. Better quality of
the reconstructed images can be achieved by our algorithm which is based on
NFFTs. For details see \cite{PoSt01IMA,PoSt00SPIE,PoSt02JFAA} and references
therein, for examples we refer to \verb+applications/radon/+.
Another application of the discrete Radon transform is the \emph{discrete
ridgelet transform}, see e.g. \cite{CaDeDoYi} and the references therein.
A simple test program for denoising images by applying hard thresholding to
ridgelet coefficients \cite{FeMa05} can be found in \texttt{applications/radon}.
It uses the NFFT-based discrete Radon transform and the translation-invariant
discrete Wavelet transform from the \textsc{MatLab} toolbox WaveLab850
\cite{WaveLab}.
%-------------------------------------------------------------------------------
%\subsection{Computation of the polar FFT}
%-------------------------------------------------------------------------------
Our last example to be mentioned here is the \emph{polar FFT}, which is a special case
of the NFFT for a particular set of nodes.
Of course, the polar as well as a so-called pseudo-polar FFT can be calculated
efficiently accurately with the NFFT.
Furthermore, the reconstruction of a $2d$ signal from its Fourier transform
samples on a (pseudo-)polar grid by means of the inverse nonequispaced FFT is
possible under certain density assumptions.
For details see \cite{AvCoDoElIs,FeKuPo06,BeKuMo07}. Numerical tests can be
found in the directory \verb+applications/polarFFT/+.

\section{Installation} \label{sect:inst}
%-------------------------------------------------------------------------------
The installation of the NFFT~3 software library follows the usual GNU
principles.
Download the most recent version from
\verb"http://www.tu-chemnitz.de/~potts/nfft".
We assume that you use a \verb"bash" compatible shell. Uncompress the archive
and
change to the newly created directory:
\begin{verbatim}
tar xfvz nfft3.x.x.tar.gz
cd nfft3.x.x
\end{verbatim}
%Before you compile and install the library, you might want to adjust the
%environment variables \verb"CPPFLAGS" and \verb"LDFLAGS" so that NFFT~3 can find
%the FFTW library if it has been installed in a non-standard location and/or if
%the NFFT~3 library shall be compiled with specific compiler flags. Leave this
%step
%out, if you are unsure what to do. Return to this step if the configure script,
%the compiler or the linker complain about missing files or libraries. Here is
%an example that adds the compiler flag \verb"-O3" for optimisations and
%adds a path to include files and libraries in a non-standard location:
%\begin{itemize}
% \itemsep-1ex
% \item
% \verb+export CPPFLAGS="$(CPPFLAGS) -O3 -I/path/to/include/files"+
% \item \verb+export LDFLAGS="$(LDFLAGS) -L/path/to/libraries"+
%\end{itemize}
Figure \ref{nfft:fig:svn} gives an overview over the directory structure of
the NFFT~3 package.
\begin{figure}[tp]%tb!]
\centering
\input{tree}
\caption{Directory structure of the NFFT~3 package.
\label{nfft:fig:svn}}
\end{figure}
The package is now ready to be configured. To this end, run the configure script
\verb"configure" which will adapt the build process to your computer system.
After that, compile the library by invoking the \verb"make" utility:
\begin{verbatim}
./configure
make
\end{verbatim}
When the build process has finished, you can run \verb"make install" to install the
library permanently on your system.
%If for example \verb"/usr" is your default installation directory,
%\verb"make install"
%will copy the NFFT~3 library to \verb+/usr/lib+, the C header files to
%\verb+/usr/include/nfft+ and the documentation together with all examples and
%applications to \verb+/usr/share/nfft+.
For more information about options offered by the \verb"configure" script,
run the script with the option \verb+--help+. For example, to change the
installation location you can use the \verb"--prefix".
Here is a short list of some important options:
By default, NFFT~3 uses the Kaiser-Bessel window function
(see Appendix \ref{appendix.nfft}). This can be changed
by passing the option \verb"--with-window=ARG",
where \verb"ARG" is replaced by one of \verb"kaiserbessel" (Kaiser-Bessel),
\verb"gaussian" (Gaussian), \verb"bspline" (B-spline), or
\verb"sinc" (sinc power). This makes all routines use the
respective window function.
NFFT~3 routines can also be configured to measure the computation time for
several steps during execution. You can enable this behavior with
the options
\verb"--enable-measure-time" and/or \verb"--enable-measure-time-fftw".
%-------------------------------------------------------------------------------
\section{NFFT - nonequispaced fast Fourier transform}
\label{appendix.nfft}
%-------------------------------------------------------------------------------
In this section, we describe the approximate NFFT algorithm in more detail.
To illustrate the principles, we restrict ourselves to the one-dimensional
case, hence the computation of
\begin{align}
\label{trigPoly1d}
f\left(x\right) & = \sum_{k\in I_{N}} \hat{f}_k \eim{k x} &
(j=0,\hdots,M-1)
\end{align}
for nonequispaced nodes $x_j \in \T$.
In this case, the NFFT has cost
${\cal O}\left(N \log N + |\log \varepsilon|
M\right)$, where $\varepsilon$ is the desired accuracy.
The chief idea of the NFFT algorithm is to use standard FFTs in combination with
an approximation scheme that is based on a window function $\varphi$. This function needs to
be mutually well localized in time/spatial and frequency domain.
%$\mathbb{R}$ and at the same time also in the frequency domain $\mathbb{R}$.
Several such window functions have been proposed in
\cite{duro93,bey95,st97,Fou02,fesu02}.
\subsection*{The ansatz}
The first step is to approximate the trigonometric polynomial $f$ of degree
$N$ in \eqref{trigPoly1d} by a linear combination $s_{1}$ of shifted
one-periodic window functions $\tilde \varphi$,
\begin{equation}\label{s1}
s_1\left(x\right) := \sum_{l \in I_n} g_{l} \; \tilde \varphi\left(x -
\frac{l}{n}\right) \,,
\end{equation}
where $n:=\sigma N$ for some oversampling factor $\sigma >1$. The value of $n$ determines the
length of the ordinary FFT used below.
\subsection*{The window function}
The window function $\varphi:\R\rightarrow\R$ is chosen so that
the one-periodic version
$
\tilde \varphi\left(x\right):=\sum_{r \in \Z} \varphi\left(x+r\right)
$
has a uniformly convergent Fourier series
$
\tilde \varphi\left(x\right)=
\sum_{k\in \Z} c_k\left(\tilde\varphi\right) \eim{k x},
$
and at the same time is well localized in the time/spatial domain $\T$
and in the frequency domain $\mathbb{Z}$.
The Fourier coefficients $c_k\left( \tilde \varphi \right)$ of this one-periodic version are samples
of the Fourier transform $\hat \varphi$ of the original window function at integers
points, i.e.,
\begin{align*}
c_k\left( \tilde \varphi \right)
& :=\int\limits_{\T} \tilde \varphi \left(x\right) \eip{k x} \, {\rm d} x
= \int\limits_{\mathbb{R}} \varphi \left(x\right) \eip{k x} \, {\rm d} x
=: \hat \varphi \left(k\right) & (k\in\Z).
\end{align*}
An example is shown in Figure \ref{fig:window_fun}.
\begin{figure}[tp]
\centering

\caption{Example for a suitable window function, in this case the

pass, transition, and stop band for $N=24,\,\sigma=\frac{4}{3},\,n=32$.}
\label{fig:window_fun}
\end{figure}
\subsection*{The first approximation - cut-off in frequency domain}
If we take the definition in \eqref{s1} and switch to the frequency domain, we obtain
\begin{equation*}
s_1\left(x\right)
=\sum_{k \in I_n} \hat g_k \, c_k\left(\tilde \varphi\right) \, \eim{k x}
+\sum_{r \in \Z \backslash \left\{0\right\}} \sum_{k \in I_n} \hat g_k \,
c_{k + n r} \left(\tilde \varphi\right) \, \eim{(k + n r)x }
\end{equation*}
with discrete Fourier coefficients
\begin{equation} \label{coeff}
\hat g_k = \sum_{l \in I_n} g_l \, \eip{\frac{k l}{n}}.
\end{equation}
A comparison of \eqref{trigPoly1d} and \eqref{s1} suggests to
define
\begin{equation} \label{coeff2}
\hat g_k :=
\begin{cases}
\frac{\hat f_k}{c_k \left(\tilde \varphi\right)} & \text{for $k \in I_N$},
\\[1ex]
0 & \text{for $k \in I_n \backslash I_N$},
\end{cases}
\end{equation}
assuming that $c_k\left(\tilde\varphi\right)$ is small for $|k| \ge n-\frac{N}{2}$.
The values $g_l$ can now be computed by applying the Fourier inversion theorem
to \eqref{coeff}. This step can be realized by an FFT of length $n$.
This first approximation causes an aliasing error.
\subsection*{The second approximation - cut-off in time/spatial domain}
If the window function $\varphi$ is well localized in time/spatial domain then it can be
approximated by a truncated version
\begin{equation*}
\psi\left(x\right):=\varphi\left(x\right) \chi_{[-{\frac{m}{n}},
{\frac{m}{n}}]}\left(x\right),
\end{equation*}
with ${\rm supp} \, \psi = \left[-{\frac{m}{n}},{\frac{m}{n}}\right], \;m \ll
n,\; m\in \N$.
Here too, we can define a one periodic version $\tilde \psi$ with compact support
in $\T$ by
$
\tilde \psi\left(x\right)=\sum_{r \in \Z} \psi\left(x+r\right).
$
With the help of the index set
$
I_{n,m} \left(x_j\right) := \left\{ l \in I_n : n x_j - m \le l \le n x_j +
m \right\}
$
a further approximation to the first approximation $s_1$ at the nodes $x_{j}$ can be defined by
\begin{equation} \label{approx}
s\left(x_j\right) :=
\sum_{l \in I_{n,m}\left(x_j\right) } g_l \,
\tilde\varphi\left(x_j - {\frac{l}{n}}\right) =
\sum_{l \in I_n } g_l \,
\tilde\psi\left(x_j - {\frac{l}{n}}\right) \, .
\end{equation}
Note, that for fixed $x_j\in \T$, the above sum contains at most
$(2m+1)$ nonzero summands.
This second approximation causes a truncation error.
\subsection*{The case $d>1$}
The described approximation method can be generalized to arbitrary dimensions.
But first, a few generalizations have to be introduced.
A multivariate window function is now defined by
$\varphi\left(\mathbf{x}\right):=\prod_{t=0}^{d-1} \varphi_t\left(x_t\right)$
with a univariate window function $\varphi_t$.
A simple consequence is that the Fourier coefficients have the form $c_{\mathbf{k}}\left(\tilde \varphi\right) =
\prod_{t=0}^{d-1} c_{k_t}\left(\tilde \varphi_t\right)$.
The ansatz function $s_{1}$ reads now
\begin{equation*}
s_1\left(\mathbf{x}\right) := \sum_{\mathbf{l} \in I_{\mathbf{n}}}
g_{\mathbf{l}} \; \tilde
\varphi\left(\mathbf{x} - \mathbf{n}^{-1}\odot\mathbf{l}\right).
\end{equation*}
The size of the FFT size is determined to $\mathbf{n}:=\mathbf{\sigma} \odot
\mathbf{N}$, and the oversampling factor is
$\mathbf{\sigma}=\left(\sigma_0,\hdots,\sigma_{d-1}\right)^{\top}$.
Following \eqref{coeff2} we define
\begin{equation*}
\hat g_{\mathbf{k}} := \left\{
\begin{array}{ll}
\frac{\hat f_{\mathbf{k}}}{c_{\mathbf{k}} \left(\tilde \varphi\right)}
& \text{for
} \mathbf{k} \in I_{\mathbf{N}} , \\[1ex]
0 & \text{for } \mathbf{k} \in I_{\mathbf{n}} \backslash I_{\mathbf{N}}.
\\
\end{array}
\right.
\end{equation*}
The values $g_{\mathbf{l}}$ are obtained by a (multivariate) FFT of size
$n_0\times n_1 \times \hdots \times n_{d-1}$.
Using the compactly supported function $\psi\left(\mathbf{x}\right)=\varphi
\left(\mathbf{x}\right)\chi_{[-{\frac{m}{n}},{\frac{m}{n}}]^d} \left(\mathbf{x}
\right)$ gives the final form,
\begin{equation*}
s\left(\mathbf{x}_j\right) := \sum_{\mathbf{l} \in I_{\mathbf{n},m}
\left(\mathbf{x}_j\right) }
g_{\mathbf{l}} \, \tilde\varphi\left(\mathbf{x}_j - \mathbf{n}^{-1}\odot
\mathbf{l}\right) =
\sum_{\mathbf{l} \in I_{\mathbf{n}} }
g_{\mathbf{l}} \, \tilde\psi\left(\mathbf{x}_j - \mathbf{n}^{-1}\odot
\mathbf{l}\right)\,.
\end{equation*}
Again, $\tilde \psi$ denotes the one-periodic version of $\psi$.
Note that the multi-index set
$
I_{\mathbf{n},m} \left(\mathbf{x}_j\right) := \left\{ \mathbf{l} \in
I_{\mathbf{n}} : \mathbf{n}
\odot \mathbf{x}_j - m \mathbf{1} \le \mathbf{l} \le \mathbf{n} \odot
\mathbf{x}_j + m
\mathbf{1}\right\}
$
has at most $(2m+1)^d$ entries for every $\mathbf{x}_j$.
\subsection*{The final algorithm}
The NFFT algorithm is given in pseudo-code in Algorithm~\ref{algo:nfft}. In
addition to the evaluation of the window functions, it requires roughly
$|I_{\mathbf{N}}|+|I_{\mathbf{n}}| \log |I_{\mathbf{n}}| + 2(2m+1)^d M$
floating point operations.
In matrix-vector notation, Algorithm~\ref{algo:nfft} can be written as
$
\mathbf{A} \mathbf{\hat{f}} \approx \mathbf{D} \mathbf{F} \mathbf{B}
\mathbf{\hat{f}},
$
where $\mathbf{B}$ denotes the sparse real $M \times
\left|I_{\mathbf{n}}\right|$
matrix
\begin{equation*} \label{spB}
\mathbf{B} := \left( \tilde\psi\left(\mathbf{x}_j - \mathbf{n}^{-1}\odot
\mathbf{l}\right)
\right)_{j=0,\hdots,M-1;\, \mathbf{l}\in I_{\mathbf{n}}}.
\end{equation*}
The matrix
$\mathbf{F}:=(\eim{\mathbf{k}(\mathbf{N^{-1}}\odot\mathbf{j})})_{\mathbf{j},
\mathbf{k}\in I_{\mathbf{n}}}$ is the ordinary Fourier matrix of size
$\left|I_{\mathbf{n}}
\right| \times
\left|I_{\mathbf{n}}\right|$ and $\mathbf{D}$ is a real $\left|I_{\mathbf{n}}
\right|
\times |I_{\mathbf{N}}|$ ``diagonal'' matrix defined by
\begin{equation*}
\mathbf{D} := \bigotimes_{t=0}^{d-1} \left(\mathbf{O}_t \, | \, \mbox{diag}
\left(1/\,
c_{k_t}\left(\tilde \varphi_t\right)\right)_{k_t\in I_{N_t}} \, | \,
\mathbf{O}_t \right)^{\top}
\end{equation*}
with zero matrices $\mathbf{O}_t$ of size $N_t \times \frac{n_t-N_t}{2}$.
The corresponding adjoint matrix-vector product is given by
$
\mathbf{A}^{\adj} \mathbf{\hat{f}} \approx \mathbf{B}^{\top}
\mathbf{F}^{\adj}
\mathbf{D}^{\top} \mathbf{\hat{f}}
$.
With the help of the transposed index set
$
I_{\mathbf{n},m}^{\top}(\mathbf{l}) := \{j=0,\hdots,M-1 :
\mathbf{l}-m
\mathbf{1} \le \mathbf{n} \odot \mathbf{x}_j \le \mathbf{l}+m \mathbf{1}
\}
$,
one obtains Algorithm~\ref{algo:nfftH} for the adjoint NFFT.

\section{Available window functions and evaluation techniques}
\label{sect:windows}
%-------------------------------------------------------------------------------
For clarity of the presentation, we restrict ourselves to the case $d=1$, again.
To keep the aliasing error and the truncation error small, several functions
$\varphi$ with good localization in time and frequency domain have been
proposed,
e.g. the (dilated) \emph{Gaussian} \cite{duro93,st97,DuSc} (with shape
parameter $b := \frac{2\sigma}{2 \sigma -1} \frac{m}{\pi}$),
\begin{align}
\label{gaussian}
\varphi\left(x\right)
& =
\left(\pi b\right)^{-1/2} \,
{\rm e}^{-\frac{\left(nx\right)^2}{b}}
, &
\hat \varphi \left(k\right)
& =
\frac{1}{n} \, {\rm e}^{-b\left(\frac{\pi k}{n}\right)^2},
\intertext{
(dilated) \emph{cardinal central $B$--splines} \cite{bey95,st97},}
\label{bspline}
\varphi\left(x\right)
& =
M_{2m}\left(n x\right), &
\hat \varphi \left(k\right)
& =
\frac{1}{n} \sinc^{2m} \left( k \pi/n\right),
\intertext{where $M_{2m}$ denotes the centered cardinal $B$--Spline of order $2m$,
(dilated) \emph{Sinc functions} \cite{pottshabil},}
\label{sinc}
\varphi\left(x\right)
& =
\frac{N\left(2\sigma-1\right)}{2m} \sinc^{2m} \left(\frac{\left(\pi N x
\left(2\sigma-1\right)\right)}{2m} \right), &
\hat \varphi \left(k\right)
& =
M_{2m}\left(\frac{2mk}{\left(2\sigma-1\right)N}\right),
\end{align}
and
(dilated) \emph{Kaiser--Bessel functions} \cite{Ja,Fou02} (with shape
parameter $b := \pi \left(2 - \frac{1}{\sigma} \right)$),
\begin{equation}
\label{kaiser}
\begin{aligned}
\varphi\left(x\right)
& = \frac{1}{\pi}
\begin{cases}
\ds \frac{\sinh\left(b\sqrt{m^2 - n^2 x^2}\right)}{\sqrt{m^2 - n^2 x^2}},
& \text{for $|x| \le \frac{m}{n}$},
\\[4ex]
\ds \frac{\sin\left(b\sqrt{n^2 x^2 - m^2}\right)}{\sqrt{n^2 x^2-m^2}},
& \text{otherwise},
\end{cases}
\\[1ex]
\hat \varphi \left(k\right)
& = \frac{1}{n}
\begin{cases}
\ds I_0 \left(m \sqrt{b^2 - \left(2 \pi k/n \right)^2} \right),
& \text{for $k= -n \left(1-\frac{1}{2\sigma} \right), \ldots,n \left(1-\frac{1}{2\sigma}\right)$},
\\
0, & \text{otherwise},
\end{cases}
\end{aligned}
\end{equation}
where $I_0$ denotes the \emph{modified order-zero Bessel function}.
For these functions $\varphi$ it has been proved that
\[
|f\left(x_j\right) - s\left(x_j\right)| \le
C\left(\sigma,m\right) \sum_{k\in I_N} |\hat{f}_k|,
\]
where
\[
C\left(\sigma,m\right) :=
\begin{cases}
4 \, \e^{-m \pi \left(1-1/\left(2\sigma-1\right)\right)}, & \text{for \eqref{gaussian}},
\\
4 \, \left(\frac{1}{2\sigma -1} \right)^{2m}, & \text{for \eqref{bspline}},
\\[1ex]
\frac{1}{m-1}\left(\frac{2}{\sigma^{2m}}+\left(\frac{\sigma}{2\sigma-1}\right)^{2m}\right), &
\text{for \eqref{sinc}},
\\[1ex]
4\pi\left(\sqrt{m}+m\right)\sqrt[4]{1-\frac{1}{\sigma}} \, \e^{-2 \pi m \sqrt{1-1/\sigma}}, &
\text{for \eqref{kaiser}}.
\end{cases}
\]
Thus, for fixed $\sigma >1$ the approximation error introduced by the NFFT
decays exponentially with the number of summands $m$ in \eqref{approx}.
These estimates can of course be generalized to higher dimensions; see \cite{elst}.
It must be noted that the cost of the NFFT also increases with $m$.
In the following, we will suggest different methods for efficient storage and
application of the matrix $\mathbf{B}$. These are all available in the
NFFT~3 library by choosing particular flags during the initialization phase.
%These methods do not yield a different asymptotic performance but rather yield
%a lower constant in the amount of computation.
\subsection*{Fully precomputed window function}
An obvious possibility is to precompute all values $\varphi(\mathbf{x}_j -
\mathbf{n}^{-1}\odot\mathbf{l})$ for $j=0,\hdots,M-1$ and $\mathbf{l}\in
I_{\mathbf{n},m} (\mathbf{x}_j)$ which are needed for $\mathbf{B}$.
This needs to store the possibly large amount of $(2m+1)^d M$ real numbers.
On the other hand, no additional computation is required during the matrix-vector
multiplication apart from the inevitable $2(2m+1)^d M$ floating point operations.
%Furthermore, we store for this method explicitly the row and column index for
%each nonzero entry of the matrix $\mathbf{B}$.
This method, indicated by the flag \texttt{PRE\_FULL\_PSI}, is the fastest procedure
but can only be used if enough memory for storage is available.
\subsection*{Tensor product based precomputation}
Using the fact that the window functions are represented by tensor products one can
resort to storing only the values $\varphi_t((\mathbf{x}_j)_t - \frac{l_t}{n_t})$ for
$j=0,\hdots,M-1$, $t=0,\hdots,d-1$, and $l_t\in I_{n_t,m} ((\mathbf{x}_j)_t)$,
where $(\mathbf{x}_j)_t$ denotes the $t$th component of the $j$th node.
This method needs to store $d(2m+1)M$ real numbers which is less than the first method needs.
However, for each node one possibly needs up to $2(2m+1)^d$ extra multiplications to
obtain the values of the multivariate window function
$\varphi(\mathbf{x}_j - \mathbf{n}^{-1}\odot\mathbf{l})$ for $\mathbf{l}\in
I_{\mathbf{n},m}(\mathbf{x}_j)$.
This technique is available for every window function discussed
and can be used by setting the flag \texttt{PRE\_PSI}. This is also the
default method used in our library.
\subsection*{Linear interpolation from a lookup table}
For a large number of nodes $M$, the amount of memory can be further reduced
by using lookup table techniques.
For a recent example within the framework of gridding see \cite{BeNiPa05}.
We suggest to precompute from the even window function the equidistant samples
$\varphi_t(\frac{rm}{Kn_t})$ for $t=0,\hdots,d-1$ and $r=0,\hdots,K$,
$K\in\N$. Then for the actual node $\mathbf{x}_j$ during the NFFT
the values $\varphi_t((\mathbf{x}_j)_t - \frac{l_t}{n_t})$ for
$t=0,\hdots,d-1$ and $l_t\in I_{n_t,m} ((\mathbf{x}_j)_t)$ are computed
by linear interpolation from its two neighboring values.
This method needs to store only $dK$ real numbers in total, where $K$
depends only on the desired accuracy but neither on the number of
nodes $M$ nor on the multibandwidth $\mathbf{N}$.
If we choose $K$ to be a multiple of $m$, we can further reduce the computational
costs during the interpolation step since the distance from $(\mathbf{x}_j)_t-
\frac{l_t}{n_t}$ to the two neighboring values is the same for all
$l_t\in I_{n_t,m}((\mathbf{x}_j)_t)$.
During the actual multiplication with the matrix $\mathbf{B}$, this method requires
$2(2m+1)^d$ extra multiplications per node. It can be used by setting the flag
\texttt{PRE\_LIN\_PSI}. Error estimates for this additional
approximation are given in \cite{KuPo06}.
\subsection*{Fast Gaussian gridding}
Two useful properties of the Gaussian window function \eqref{gaussian} that can be exploited
within the presented framework have recently been reviewed in \cite{GrLe04}.
Beside the tensor product structure for $d>1$, which is also valid for all other
window functions, it is remarkable that the number of evaluations of the
exponential function \texttt{exp()} can be reduced by a substantially.
More precisely, for $d=1$ and a fixed node $x_j$ the evaluation of
$\varphi(x_j-\frac{l'}{n})$, $l'\in I_{n,m}(x_j)$ can be computed more
efficiently by writing this as
\begin{equation*}
\sqrt{\pi b}\varphi\left(x_j-\frac{l'}{n}\right)
=\e^{-\frac{(nx_j-l')^2}{b}}
=\e^{-\frac{(nx_j-u)^2}{b}}
\left(\e^{-\frac{2(nx_j-u)}{b}}\right)^l
\e^{-\frac{l^2}{b}}\,,
\end{equation*}
where $u=\min I_{n,m}(x_j)$ and $l=0,\hdots,2m$.
The first factor and the exponential within the brackets are a
constant for each fixed node $x_j$.
Once we have evaluated the second exponential, its $l$th power can be computed
by repeated multiplications only.
Furthermore, the last exponential is independent of $x_j$ such that these $2m+1$
different values need to be precomputed only once -- usually a negligible amount.
Thus, it is sufficient to store or evaluate $2M$ exponentials for $d=1$.
The case $d>1$ needs to store or evaluate $2dM$ numbers. This follows from the
tensor product structure.
The described method is employed when the flags \texttt{FG\_PSI} and possibly
\texttt{PRE\_FG\_PSI} are used.
\subsection*{No precomputation of the window function}
The last method considered does not precompute any values of the window function
at all. Instead, all values are calculated on-line. This needs to be done at most
$\frac{3}{2}(2m+1)^d M$ times. The computation time strongly depends on how fast
one can evaluate the particular window function. Since this method does not need
any additional storage, it is attractive whenever large problems are considered
that would push the other methods beyond the memory limitations.
%-------------------------------------------------------------------------------
\section{Further NFFT approaches}\label{A.4}
%-------------------------------------------------------------------------------
Besides \cite{nfft3}, the {\sc MatLab} toolbox \cite{fematlab} also implements
the NFFT.
In several papers, approximations techniques similar to the NFFT have been
described.
Common names for these schemes are
\emph{non-uniform fast Fourier transform} \cite{fesu02},
\emph{generalized fast Fourier transform} \cite{duro93},
\emph{unequally-spaced fast Fourier transform} \cite{bey95},
\emph{fast approximate Fourier transforms for irregularly spaced data}
\cite{ware98},
\emph{non-equispaced fast Fourier transform} \cite{Fou02} or
\emph{gridding} \cite{scsc,Ja,Pe}.
Also, different window functions have been considered in various papers, e.g. a Gaussian
pulse tapered with a Hanning window \cite{DuSc}, Gaussian kernels combined
with Sinc kernels \cite{Pe}, and particular optimized windows \cite{Ja,DuSc}.
Special approaches based on scaling vectors \cite{NgLi99}, minimizing
the Frobenius norm of certain error matrices \cite{st01}, or min-max
interpolation \cite{fesu02} have been proposed.
While these approaches lead to better accuracy for the Gaussian or B-Spline
windows, improvements for the Kaiser-Bessel window are marginal.
Recently, the time consuming multiplication with the matrix $\mathbf{B}$ has
been accelerated by using commodity graphics hardware \cite{SoScNoHa08}.
The following two approaches have also been considered for the
univariate case \hbox{$d=1$:}
The authors of \cite{AnDa96} use for each node $x_j$ an $m$th order Taylor
expansion of the trigonometric polynomial \eqref{trigPoly1d} around the nearest
neighboring point on an oversampled equispaced lattice $I_n/n$. Here again we have
$n=\sigma N,\, \sigma\gg 1$.
This algorithm utilizes $m$ FFTs of size $n$ (compared to only one in our approach)
and uses a fair amount of extra memory; see also \cite{KuPo06,Ku08GAMM}.
Another approach is considered in \cite{DuRo95}. It is based on a Lagrange
interpolation technique.
After computing an FFT of the vector $\mathbf{\hat{f}}\in\C^N$ in \eqref{eq:nfft}
an exact polynomial interpolation scheme is used to obtain the values of the
trigonometric polynomial $f$ at the nonequispaced nodes $x_j$.
This is the most time consuming part of this method. In an approximate way,
it can however be realized with the help of the fast multipole method.
This approach is appealing since it allows also for computing an
inverse transform.
Nevertheless, numerical experiments in \cite{DuRo95} indicate that this
approach is far more time consuming than Algorithm \ref{algo:nfft}. Also, the
inversion can only be computed in a stable way for almost equispaced nodes
\cite{DuRo95}.
For a comparison of different approaches to nonequispaced Fourier transforms, we also
refer to \cite{ware98,st01,fesu02,KuPo06}.

\vspace{-8ex}
Fast Fourier transforms (FFTs) belong to the ``10 algorithms with the greatest
influence on the development and practice of science and engineering in the
20th century'', cf.~\cite{DoSu00}.
The classic algorithm in \cite{CoTu65} computes the discrete
Fourier transform
\begin{equation*}
f_j= \sum_{k=-\frac{N}{2}}^{\frac{N}{2}-1} \hat{f}_{k} \eim{\frac{kj}{N}}
\end{equation*}
for $j=-\frac{N}{2},\hdots,\frac{N}{2}-1$ and given complex coefficients
$\hat{f}_{k}\in\C$.
Using a divide and conquer approach, the number of floating point operations
is reduced from $\cO(N^2)$ for a straightforward computation to only
$\cO(N\log N)$.
In conjunction with publicly available efficient implementations
\cite{FFTW05}, the fast Fourier transform has become of great importance in
scientific computing.
Its applications include for example digital signal and image processing as
well as the numerical solution of differential and integral equations.
The author of \cite[p. ix]{loan} summarises ``life as we know it
would be very different without the FFT''.
However, two shortcomings of traditional schemes are the need for equispaced
sampling and the restriction to the system of complex exponential functions.
During the last two decades, both problems have attracted much attention.
We refer to \cite{maro96} for an introduction to discrete Fourier analysis
with orthogonal polynomials, spherical harmonics, and more general functions.
The second branch of generalisations dispenses with the need for equispaced
sampling and establishes so-called nonequispaced FFTs, see
e.g. \cite{postta01}.
The common concept in most generalised fast Fourier transforms - and other
algorithms for the computation with dense matrices - is the use of
approximation schemes.
The functions involved, e.g. the complex exponentials, are replaced by
approximations with prescribed accuracy that allow for the design of a fast
algorithm.
We trade exactness for efficiency; instead of precise computations, the
proposed methods guarantee a given target accuracy.
The principal contribution of the present software package is a publicly
available implementation of various fast algorithms for discrete Fourier
transforms.
For notational convenience let the multi-index set
\begin{equation*}
I_{\zb N} = \left\{ \zb k=\left(k_t\right)_{t=0,\hdots,d-1} \in \Z^d: -
\frac{N_t}{2} \le k_t < \frac{N_t}{2} ,\;t=0,\hdots,d-1\right\},
\end{equation*}
with $\zb N=\left(N_t\right)_{t=0,\hdots,d-1}\in 2\N^d$ be given.
For given Fourier coefficients $\hat f_{\zb k} \in \C$, $\zb k \in I_{\zb N}$,
and arbitrary nodes $\zb x_j \in [-1/2,1/2)^d$, $j=0,\hdots,M-1$, we consider
the computation of
\begin{equation*}
f\left(\zb x_j\right) = \sum_{\zb k\in I_{\zb N}} \hat{f}_{\zb k} \eim{\zb
k\zb x_j},\quad j=0,\hdots,M-1.
\end{equation*}
Obviously, the straightforward algorithm for this task takes $\cO(M|I_{\zb
N}|)$ floating point operations.
In contrast, the {\em nonequispaced fast Fourier transform} computes the above
sums up to a user-specified accuracy in $\cO(|I_{\zb N}|\log|I_{\zb N}|+M)$
operations.
The implemented routines are state-of-the-art with respect to recently
suggested improvements, see e.g. \cite{GrLe04}, and use the highly efficient
FFTW library \cite{FFTW05}.
The generalisations of the NFFT include fast algorithms for several discrete
Fourier transforms.
Due to its relevance in tomography, geophysics, and meteorology, we would like
to highlight the nonequispaced fast spherical Fourier transform (NFSFT).
In analogy to the complex exponentials $\mathrm{e}^{\mathrm{i} k x}$ on the
torus, the spherical harmonics $Y_k^n$ form the orthogonal Fourier basis with
respect to the usual inner product on the sphere.
For given Fourier coefficients $\hat f_k^n \in \C$ and arbitrary nodes
with longitude $\vartheta_j\in[0,\pi]$ and latitude $\varphi_j\in [0,2\pi)$,
we are interested in the evaluation of
\begin{equation*}
f\left(\vartheta_j,\varphi_j\right) =
\sum_{k=0}^N \sum_{n=-k}^k \hat f_k^n
Y_{k}^n\left(\vartheta_j,\varphi_j\right),\quad j=0,\hdots,M-1.
\end{equation*}
Here, our implemented scheme reduces the computational costs from $\cO(MN^2)$
operations to only $\cO(N^2\log^2 N+M)$.
Further fast transforms include the Fourier transforms with nonequispaced data
in time and frequency domain, real trigonometric transforms, and sparse FFTs.
All these Fourier transforms come along with their adjoint algorithms, used in
quadrature rules for example, and inverse transforms as used for scattered
data approximation.
The NFFT and its generalisations have found a lot of applications, where the
current release of the library includes various fast summation methods,
reconstruction algorithms in medical imaging, and the polar FFT as part of our
ridgelet transform.
We would like to highlight the fast summation method, because this problem
arises in integral equations or potential theory.
In particular, our method proves comparable with the celebrated fast multipole
method \cite{greenrokh87}.
The documentation of our library is split into two parts:
The tutorial \cite{nfft3_tutorial} surveys the fast Fourier transform at
nonequispaced nodes, its generalisations, and inversion.
Moreover it provides an overview over the C library which allows users to
compute their first transforms by using simple interfaces to the computational
kernels.
The detailed documentation (part of the source tree) of all user functions,
options and parameters is done with Doxygen \cite{doxygen} and allows for
further optimisation with respect to speed, accuracy, and memory usage.

\section*{Referee 2}
\label{sect:1}
\begin{itemize}
\item
\begin{quote}
Referee: The performance of the
library is not comparable to high performance libraries such as FFTW but
it should still be reasonable for many applications. Improving performance
would still be desirable of course.
\end{quote}
We generally acknowledge that performance and software design improvements
are desirable. But NFFT 3 is for the major part the result of recent
research and as such has not been around for a long time.
\item
\begin{quote}
Referee: As I see it, there are 3 'layers' that are relevant for a
library: 1) underlying theory and algorithms (the math behind it)
2) the actual implementation (what exact specifications have been used and
why, some pseudo code, what optimization techniques have been used, which
algorithms and why, arithmetic cost and performance analysis, maybe other
analyses, etc.) 3) how to install and use the library (Makefiles,
concrete code examples) In a library paper I would expect a short version
of 1) as background, 2) as the focus and then 3) very briefly.
\end{quote}
In the terminology of TOMS, this paper is a \emph{research paper} and not a
\emph{library paper}. The aim of the article is to give a mathematical
description of the algorithms implemented in the NFFT 3 software library
with some more mathematical background on the core NFFT algorithm. A second
goal is to mention some applications of the implemented methods.
The focus of this paper is not the description of technical details of the
implementation (code optimizations, software engineering concerns,...) and
the full programming interface.
\item
\begin{quote}
Referee:
As it is right now the authors put the emphasis on 3) (including details
on how to untar a file that is really way too much) and have some of 2)
in the appendix, but not enough. Also, the cost and performance analysis
is far too brief for a library paper.
\end{quote}
We have shortened the installation instructions. They have also been moved
to Appendix A.1.
As mentioned, our aim is not to describe all details of the implementation.
But we now summarise performance related tests in Section 5. The focus is
to observe how the NFFT algorithm does behave in comparison to the
direct implementation.
It is nevertheless true that more extensive numerical tests at a
mature state of the library are desirable. At the current stage, an
extensive and in-depth performance analysis is not available.
\item
\begin{quote}
Referee:
Concrete, I recommend (following my above numbering) to have a
background section on 1), then all relevant details on 2) (some of which are
not in the paper) and then a very short section, or appendix, on 3). (The
authors may want to look at some existing library papers of popular
libraries.) Further, there have to be more details on the relevant
implementation decisions, optimization techniques performed, and, most
important, a more extensive evaluation of operations count and runtime
performance (which should be given also in Gflop/s or pseudo Gflop/s, i.e.,
a number of ops is stipulated in case the exact one is not available).
\end{quote}
Section 2 has been extended to start with the classical discrete Fourier
transform (DFT) and mention more relevant properties of the NFFT algorithm.
Details are found in the Appendices A.2 and A.3.
\item
\begin{quote}
Referee: Detailed comments \ldots
\end{quote}
In the text, the library is now consistently denoted NFFT 3. We include the
major version number in the name since earlier versions offered
substantially less functionality. The rest of the comments have been
incorporated into the paper and all mentioned mistakes have been fixed.
\end{itemize}

``Using NFFT~3 -- a software library for various nonequispaced fast
Fourier transforms''

}
\begin{letter}{Editor-in-Chief\\
Prof. Ian Gladwell\\
Department of Mathematics\\
Southern Methodist University\\
Dallas, TX 75275 USA}
\opening{Dear Professor Gladwell,}
we thank all three referees for their helpful comments and valuable
suggestions. In the following we report on the changes.
\textbf{Referee 1}
No changes.
\textbf{Referee 2}
The structure of the paper has been kept, in particular Section 3.2 shows the
typical workflow and details on the precomputation are still in the appendix.
The following suggestions of the referee have been incorporated, 1), 4), 5),
and 6).
2) ``Usually $\hat f$ is for the FT of f and not vice versa. If you have a
good reason for doing it like this, state it.'' and p.~3, sec 2.1 of the first
report: \\
The beginning of Section 2 now states that the FFT evaluates a
trigonometric polynomial at equispaced nodes and that this point of view is
most convenient for the generalisation to nonequispaced nodes.
3) ``P.3, line -10: what do you mean by no additional memory?''
The matrix entries are explicitly given and they are computed only when used.
A more detailed cost analysis and performance analysis has been
added, see the second issue of Referee 3.
\newpage
\textbf{Referee 3}
On ``The major issues''
\begin{enumerate}
\item The Sections 3.2 and 3.4 clearly state how the nodes have to be set.
\item A more detailed cost analysis and performance analysis has been
added. In particular, Algorithm 2 and 3 give clear upper bounds on the number
of arithmetic operations excluding the evaluation of the so called window
function which is detailed in Appendix A.3. Section 5.1 specifies these costs
under the tested default settings and gives a performance plot in Figure 5.1.
\item The size of the 3D problems is considered to be reasonable on standard hardware, since an
NFFT with $128^3$ Fourier coefficients, $128^3$ evaluation nodes, oversampling
factor $2$ and disjoint FFTW-in/output arrays takes approximately
\begin{equation*}
(128^3 + 2 \times (2\times 128)^3 + 128^3) \times 16 =576 \text{MByte}.
\end{equation*}
A NFFT of size $256^3$ would already take over $4\text{GByte}$ with these
settings (the library can compute such a transform by using a smaller
oversampling factor etc. at increased cost).
\end{enumerate}
On ``The minor issues''
\begin{enumerate}
\item[1,2.] Done, except ``various $\rightarrow$ certain'', since
``Nonequispaced FFT'' is typically associated with (2.3) and ``various''
refers to the fact that more general transforms are considered as well.
\item[3.] Done, but we kept the version number when referring to the library.
\item[4,5,6,7.] Done. However, we found no inconsistent vector notation and
the terminology ``adjoint'' (or transposed) and ``inverse'' is in
accordance with [19]
\item[8.] We changed the section title. The statement on the complexity of the NDFT is correct.
\item[9.] Done, a detailed description of the precomputation is given in
Appendix A.3, the naming system follows FFTW and does not use abbreviations
like LAPACK.
\item[10.] It is more convenient to present first (up to Section 4) the
theoretical part and finally the numerical results (Section 5 and 6).
Test specifications are given in the second paragraph of Section 5.
\item[11.] Citations now follow the bibliographystyle \verb"acmtrans".
\end{enumerate}
In addition, the layout of tables has been changed to be compliant with
the ACM manuscript preparation guidelines.

Yours sincerely

\section*{Referee 1}
\label{sect:1}
\begin{itemize}
\item
\begin{quote}
Referee:
I am not so familiar with the norms in TOMS, but it seems to me that
installation instructions (section 3.1) would not have longevity that
merits archiving, and could be relegated to the online code package.
\end{quote}
We do think that readers might appreciate brief installation instructions.
They have been shortened and moved to Appendix A.1.
\item
\begin{quote}
Referee:
As an optional note, it would be convenient if the CGNR routine allowed
a user-defined preconditioner.
\end{quote}
We appreciate the suggestion and are well aware that a variety of
Toeplitz-preconditioner are possible for the CGNR routine.
However, numerical experience (in line with theoretical results) suggests
that for reasonably well-distributed point sets, solving the weighted
normal equation works well with the used ``diagonal preconditioner''
$\mathbf{W}$ and $\mathbf{\hat W}$, already.

%
% this file: Modification of chicago.sty for new ACM bibliography
% style, which is similar (but not identical) to the ``Chicago'' style.
%
% chicago.sty: Style file for use with bibtex style chicago.bst, for
% bibliographies formatted according to the 13th Edition of the Chicago
% Manual of Style.
%
% 'newapa.bst' was made from 'plain.bst', 'named.bst', and 'apalike.bst',
% with lots of tweaking to make it look like APA style, along with tips
% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.
% newapa.sty formed the basis of this style, chicago.sty. Author-date
% references in newapa.bst formed the basis for chicago.bst. Chicagoa.bst
% supports annotations.
%
% Version 4 (August, 1992):
% - fixed chicago.bst and chicagoa.bst to handle long author lists in
% sorting
% - fixed chicago.bst and chicagoa.bst so that missing page numbers in
% ``article'' entries are handled correctly
% - modified chicago.sty to format entries with 2nd and subsequent lines
% indented.
%
% Citation format: (author-last-name year)
% (author-last-name and author-last-name year)
% (author-last-name et al. year)
% (author-last-name)
% author-last-name
% author-last-name (year)
% (author-last-name and author-last-name)
% (author-last-name et al.)
% (year) or (year,year)
% year or year,year
%
% Reference list ordering: alphabetical by author or whatever passes
% for author in the absence of one.
%
% This BibTeX style has support for abbreviated author lists and for
% year-only citations. This is done by having the citations
% actually look like
%
% \citeauthoryear{full-author-info}{abbrev-author-info}{year}
%
% The LaTeX style has to have the following (or similar)
%
% \let\@internalcite\cite
% \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}

% These TeX macro definitions are found in acmtrans.sty. Additional
% commands to manipulate different components of a citation can be defined
% so that, for example, you can list author's names without parentheses
% if using a citation as a noun or object in a sentence.
%
% Features of acmtrans.bst:
% ========================
%
% - all authors appear last name first.
% - all pages are listed xx-xx, (no pp.) and are at the end of the reference
% - publishers are identified as publisher, address
% - conferences papers (inproceedings) may give city of conference,
% date of conference, and journal that the proceedings appear in.
% - months abbreviated to max four letters (eg. Mar.)
% - volume of a series indicated after the title of the series
% - editors appear after edited title and are identified by a trailing "Eds."
% not in parentheses. Editor names are not given in small caps.
% (unless there is no author line)
% - names terminated with a period even if there is no first name.
% - editions are indicated trailing after the work, not in parentheses.
% - "et al." citations have a protected period to avoid bad spacing (jrh)
% - "address" required when publisher given
% - series (roman) and volume are in a sentence separate from (book-)title
%
%
% Features of chicago.bst:
% =======================
%
% - full names used in citations, but abbreviated citations are available
% (see above)
% - if an entry has a "month", then the month and year are also printed
% as part of that bibitem.
% - all conjunctions use "and" instead of "\&"
% - major modification from Chicago Manual of Style (13th ed.) is that
% only the first author in a reference appears last name first-
% additional authors appear as J. Q. Public.
% - pages are listed as "pp. xx-xx" in all entry types except
% article entries.
% - book, inbook, and manual use "location: publisher" (or organization)
% for address and publisher. All other types list publishers separately.
% - "pp." are used to identify page numbers for all entry types except
% articles.
% - organization is used as a citation label if neither author nor editor
% is present (for manuals).
% - "et al." is used for long author and editor lists, or when "others"
% is used.
%
% Modifications and bug fixes from newapa.bst:
% ===========================================
%
% - added month, year to bib entries if month is present
% - fixed bug with In proceedings, added necessary comma after title
% - all conjunctions changed to "and" from "\&"
% - fixed bug with author labels in my.full.label: "et al." now is
% generated when "others" is an author name
% - major modification from Chicago Manual of Style (13th ed.) is that
% only the first author in a reference appears last name first-
% additional authors appear as J. Q. Public.
% - pages are listed as "pp. xx-xx" in all entry types except
% article entries. Unnecessary (IMHO) "()" around page numbers
% were removed, and page numbers now don't end with a period.
% - created chicago.sty for use with this bibstyle (required).
% - fixed bugs in FUNCTION {format.vol.num.pages} for missing volume,
% number, and /or pages. Renamed to format.jour.vol.
% - fixed bug in formatting booktitles: additional period an error if
% book has a volume.
% - fixed bug: editors usually given redundant period before next clause
% (format.editors.dot) removed.
% - added label support for organizations, if both author and editor
% are missing (from alpha.bst). If organization is too long, then
% the key field is used for abbreviated citations.
% - In proceedings or books of several volumes, no comma was written
% between the "Volume x" and the page numbers (this was intentional
% in newapa.bst). Fixed.
% - Some journals may not have volumes/numbers, only month/year (eg.
% IEEE Computer). Fixed bug in article style that assumed volume/number
% was always present.
%
