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 Appendix: 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 `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice 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. pynac-0.2.6/ChangeLog000066400000000000000000000005601212114631200143750ustar00rootroot00000000000000This file is not yet operational. Eventually it should record all changes. Till then, you are advised to resort to our CVS server where all changes are logged. This is how to get anonymous read-only access: $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC login enter the password `anoncvs' $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC -z 9 co GiNaC pynac-0.2.6/INSTALL000066400000000000000000000122311212114631200136520ustar00rootroot00000000000000PREREQUISITES ============= GiNaC requires the CLN library by Bruno Haible installed on your system. It is available from . You will also need a decent ANSI-compliant C++-compiler. We recommend the C++ compiler from the GNU compiler collection, GCC >= 3.4. If you have a different or older compiler you are on your own. Note that you may have to use the same compiler you compiled CLN with because of differing name-mangling schemes. The pkg-config utility is required for configuration, it can be downloaded from . To build the GiNaC tutorial and reference manual the doxygen utility (it can be downloaded from http://www.stack.nl/~dimitri/doxygen) and TeX are necessary. Known to work with: - Linux on x86 and x86_64 using GCC 3.4, 4.0, 4.1, and 4.2. - Linux on Alpha using GCC 3.4. - Solaris on Sparc using GCC 3.4. - Windows on x86 using GCC 3.4 (MinGW) Known not to work with: - GCC 4.3.0 due to the compiler bug, see . - GCC 2.96 or earlier because proper exception and standard library support is missing there. If you install from CVS, you also need GNU autoconf (>=2.59), automake (>=1.7), libtool (>= 1.5), bison (>= 2.3), flex (>= 2.5.33) to be installed. INSTALLATION ============ To install from a source .tar.bz2 distribution: $ ./configure $ make [become root if necessary] # make install To build the GiNaC tutorial and reference manual in HTML, DVI, PostScript, or PDF formats, use one of $ make html $ make dvi $ make ps $ make pdf To compile and run GiNaC's test and benchmark suite and check whether the library works correctly you can use $ make check The "configure" script can be given a number of options to enable and disable various features. For a complete list, type: $ ./configure --help A few of the more important ones: --prefix=PREFIX install architecture-independent files in PREFIX [defaults to /usr/local] --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX [defaults to the value given to --prefix] --disable-shared suppress the creation of a shared version of libginac --disable-static suppress the creation of a static version of libginac More detailed installation instructions can be found in the documentation, in the doc/ directory. The time the "make" step takes depends heavily on optimization levels. Large amounts of memory (>128MB) will be required by the compiler, also depending on optimization. To give you a rough idea of what you have to expect the following table may be helpful. It was measured on an Athlon/800MHz with "enough" memory: step | GCC optimization | comment | -O1 | -O2 | --------------+---------+---------+---------------------------------------- make | ~6m | ~8m | shared and static library make check | ~8m | ~12m | largely due to compilation To install from CVS =================== First, download the code: $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC login [enter "anoncvs" as the password] $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC co GiNaC $ cd GiNaC Secondly, make sure all required software is installed. This is *really* important step. If some package is missing, the `configure' script might be misgenerated, see e.g. this discussion: Finally, run $ autoreconf -i to generate the `configure' script, and proceed in a standard way, i.e. $ ./configure $ make [become root if necessary] # make install COMMON PROBLEMS =============== Problems with CLN ----------------- You should use at least CLN-1.1, since during the development of GiNaC various bugs have been discovered and fixed in earlier versions. Please install CLN properly on your system before continuing with GiNaC. Problems building ginsh ----------------------- The GiNaC interactive shell, ginsh, makes use of GNU readline to provide command line editing and history. If readline library and/or headers are missing on your system, the configure script will issue a warning. In this case you have two options: 1) (the easiest) If you don't intend to use ginsh (i.e. if you need GiNaC library to compile some piece of software), ignore it. ginsh builds just fine without readline (obviously, it won't support the command line history and editing). 2) Install GNU readline and run the configure script once again. Depending on what your system/distribution is, you will have to install a package called libreadline and libreadline-dev (or readline-devel). If your system's vendor doesn't supply such packages, go to and compile it yourself. Note that non-GNU versions of libreadline (in particular one shipped with Mac OS X) are not supported at the moment. Problems with missing standard header files ------------------------------------------- Building GiNaC requires many standard header files. If you get a configure error complaining about such missing files your compiler and library are probably not up to date enough and it's no worth continuing. pynac-0.2.6/Makefile.am000066400000000000000000000010121212114631200146500ustar00rootroot00000000000000## Process this file with automake to produce Makefile.in SUBDIRS = ginac DIST_SUBDIRS = ginac # pkg-config metadata pkgconfigdir = $(libdir)/pkgconfig pkgconfig_DATA = pynac.pc $(pkgconfig_DATA): config.status # All the rest of the distributed files EXTRA_DIST = pynac.pc pynac.spec # Rule to build tar-bzipped distribution package $(PACKAGE)-$(VERSION).tar.gz: dist # Rule to build RPM distribution package rpm: $(PACKAGE)-$(VERSION).tar.gz rpmbuild -ta --clean $(PACKAGE)-$(VERSION).tar.gz ACLOCAL_AMFLAGS=-I m4 pynac-0.2.6/Makefile.in000066400000000000000000000664141212114631200147020ustar00rootroot00000000000000# Makefile.in generated by automake 1.11.6 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011 Free Software # Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ am__make_dryrun = \ { \ am__dry=no; \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ echo 'am--echo: ; @echo "AM" OK' | $(MAKE) -f - 2>/dev/null \ | grep '^AM OK$$' >/dev/null || am__dry=yes;; \ *) \ for am__flg in $$MAKEFLAGS; do \ case $$am__flg in \ *=*|--*) ;; \ *n*) am__dry=yes; break;; \ esac; \ done;; \ esac; \ test $$am__dry = yes; \ } pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = .

Now they work on MinGW and Cygwin as well. 1.4.1 (21 November 2007) * Fixed memory leak in ginac_yylex(). * Fixed memory leaks in mul::eval() and power::eval(). * Fixed macro checking for version of libreadline (Mac OS X). * Fixed broken preprocessor instruction in excompiler.cpp. * Fixed broken module loading in excompiler.cpp. * info(info_flags::has_indices) now works for sums and products. * Improved mul::expand(). * Improved CLN output. 1.4.0 (31 August 2007) * New tinfo mechanism. * Removed rtt from class symbol. * Faster archiving by adding a map from strings to indices in the atoms vector. * Improved unarchiving: algorithms order N instead of order N^2. * Added compile function, excompiler class. * Added exset type. * Added step function to GiNaCs built-in functions. * Added is_polynomial() method. * Added real_part() and imag_part() methods. * Added matrix::is_zero_matrix() method. * Added evalm() method to pseries class. * Improved dummy index renaming. * Many improvements for class clifford. * New flag for positive symbols/numbers, added possymbol class. * Added programming examples in doc/examples 1.3.9 (21 November 2007) Backporting bug-fix release from version 1.4.1. 1.3.8 (28 August 2007) * Drop support of ginac-config and ginac.m4. Please use pkg-config instead. * atan2(y,x) branch cut correction. * Fixed bug in series expansion. * Additional transformations for mul and power. * Clifford units now honor representation labels. * Correct csrc output for idx and fderivative. * Improved handling of convergence transformationis for Li/G. * Fix compilation issues with prereleases of GCC 4.3. * info_flags::expanded added. * input_parser also accepts pow(). * texinfo.tex removed from package. 1.3.7 (05 February 2007) * Fixed bug in expansion of power. * Fixed bugs in functions S() (infinite loop), H() and zeta() (wrong results). * Rebuilt bison related files with bison version 2.3 (fixes parse error bugs). * Improved power::eval(). * Improved libreadline detection. 1.3.6 (13 December 2006) * Better worst case behavior in heuristic gcd. * Improved collecting for sparse multivariate polynomials. * Improved collect_common_factors. * Fixed bug in numerical evaluation of multiple polylogs. * Fixed numerical integration of complex functions. * Fixed bug in tensor::replace_contr_index(). 1.3.5 (17 August 2006) * Re-built bison related files that caused bugs with gcc 4. * Fixed bugs in fderivative::match_same_type(), expairseq::match(), expand_dummy_sum(), and expairseq::map(). * Fixed template specialization for class container to be gcc 4.2 compliant. * Output in csrc mode is now -x instead of -1.0*x. * Fixed tutorial and reference generation in html/pdf/ps format. * Modified autotool configuration to allow for compilation on MinGW. * Debian packaging files updated. 1.3.4 (12 April 2006) * More general index dimensions are now possible. * Improved algebraic substitutions. * Fixed wrong matching in .has(). * Fixed bug in differentiation of a power. * collect_common_factors also works with negative powers of common factors now. * Code clean-up and preparations for upcoming cln 1.2. 1.3.3 (24 October 2005) * Fixed bug occuring in algebraic substitutions with expressions involving indices. * Fixed bug that selected the wrong algorithm for determinants of purely numeric matrices with at least one floating point element. * Fixed bug in function H that caused an infinite recursion for arguments around +-I. * Fixed const-correctness in printing handler for GCC 4.0.2. * Made lookup in adaptivesimpson precision-aware. * Added series expansion for functions (classical) Li and S around x==0. * Added fsolve() numerical univariate real-valued function solver. * Added functions sub_matrix() and reduced_matrix(). * Small cleanups. Less warnings with latest GCC. 1.3.2 (10 July 2005) * GCD avoids to produce expanded expressions. * Fixed bug in expanding expressions containing dummy indices. * Fixed static initialization order bug. * collect_common_factors now works with powers. * Modernized configuration scripts. 1.3.1 (04 May 2005) * integral() and eval_integ() can be used from ginsh. * Integrals can be series-expanded. * Fixed a library initialization problem. * GiNaC compiles from tarball even if lex/flex is missing. * Fixed bugs in canonicalize_clifford(), clifford_prime() and clifford_to_lst(). * clifford_moebius_map(), remove_dirac_ONE() and LaTeX output of Clifford objects now care about representation labels. * Fixed bug in gcd. * Better output for slashed expressions 1.3.0 (19 October 2004) * The Clifford classes have been generalized to allow working with Clifford algebras generated by arbitrary symmetric tensors or matrices. Also, a lot of new functions for Clifford algebras have been added, including automorphisms and Moebius transformations. [V. Kisil] * Added some basic symbolic and numeric integration facilities. [C. Dams] * The multiple polylogarithm Li() now evaluates numerically for arbitrary arguments. * New functions G(a,y) and G(a,s,y) added (another notation for multiple polylogarithms). 1.2.4 (12 October 2004) * Added ex::unitcontprim() to compute the unit, content, and primitive parts of a polynomial in one go. * binomial(n, k) evaluates for non-integer arguments n. * Li(2,x) now evaluates for +-I. * Optimized Li(2,x). * Fixed bug in Li(n,x) (if Li(2,x) was calculated with high precision the enlargement of the look-up table caused a segmentation fault). * Fixed another bug in the series expansion of powers, and a bug in power::info(). 1.2.3 (13 August 2004) * Added variants of dirac_trace() and color_trace() that take the trace over more than one representation label by specifying a set or list of labels. * diracgamma::contract_with() uses Chisholm identities in 4 dimensions to produce more compact results. * Fixed a bug in the series expansion of powers. * The --enable-html-doc and --enable-ps-doc configure options are gone. Documentation in HTML, DVI, PostScript, and PDF formats is now built with "make html", "make dvi", "make ps", and "make pdf", respectively. The only documentation that gets built by default are the tutorial in .info format and the manpages. 1.2.2 (3 August 2004) * Added const_preorder_iterator and const_postorder_iterator classes (and associated methods ex::pre/postorder_begin/end()) providing tree traversal with iterators. * Fixed the LaTeX output of the varidx class. * Fixed bugs in series expansion and complex conjugation. * (p.i*p.i).get_free_indices() returns the correct result () instead of (.i). * Symbolic functions without any eval(), evalf() etc. functions now work properly. * integer_content(), content(), and primpart() now also work for polynomials with rational coefficients (calculating the LCM of coefficients' denominators). * Added method matrix::rank(). * Added function resultant(). * Added integer_content() function to ginsh. 1.2.1 (23 April 2004) * Fixed infinite recursion in atan2_evalf() and improved atan2_eval(). * Added automatic evaluations for trigonometric functions with negative arguments (e.g. sin(-2) -> -sin(2)). * Fixed a static initialization order goof-up. * Fixed various bugs in series expansion. 1.2.0 (19 March 2004) * Added a structure template class for the easy creation of user-defined algebraic classes. * Added support for (acyclic) visitors, to allow cleaner implementations of algebraic algorithms. * Added a const_iterator class that can be used instead of op()/nops(). * Completely revamped the implementation of expression output. It is now possible to add new output formats, to change the behavior of predefined formats at run-time, and to have different output styles for algebraic functions. * Symbols can be made non-commutative. * Added a method ex::conjugate() and a function conjugate() for complex conjugation. Symbols can be declared as real or complex-valued. * Improved the speed of subs(), normal(), to_rational() and to_polynomial() by the use of maps instead of lists. The old forms subs(const lst & ls, const lst & lr, unsigned options) to_rational/to_polynomial(lst & repl) are still available for compatibility, but using the new forms subs(const exmap & m, unsigned options) to_rational/to_polynomial(exmap & repl) is more efficient, especially when the number of replacements is large. * quo(), rem(), prem(), sprem(), decomp_rational(), unit(), content(), primpart() and matrix::charpoly() now take a "const ex &" instead of a "const symbol &". * Redundant expressions (two ex pointing to different objects are found to be equal in compare()) are now actively deleted/fused to conserve memory and speed up subsequent comparisons. This behavior can be suppressed on a per-object level with status_flags::not_shareable. Lists and matrices are not shareable by default. * Lots of internal streamlining and optimizations. * Caveats for class implementors: - basic::copy() and basic::destroy() are gone; classes derived from basic can use the defaults for the assignment operator and copy constructor. - basic::subs(), basic::normal(), basic::to_rational() and basic::to_polynomial() take 'exmap' objects instead of lists. - basic::subs() now descends into subexpressions (if accessible via nops()/op()/let_op()). If you have a custom implementation of subs() that calls basic::subs() after substituting subexpressions, this needs to be changed to a call to subs_one_level(). - lst::thislst() and exprseq::thisexprseq() renamed to thiscontainer(). - thiscontainer() and associated constructors now take a std::auto_ptr. - Overloading basic::print() is now deprecated. You should use print_func<>() class options instead. 1.1.7 (11 March 2004) * Fixed a bug in canonicalize_clifford(). * Series expansion now works predictably. All terms with the exponent of the expansion variable smaller than the given order are calculated exactly. If the series is not terminating, the Order function is (at least) of the given order. 1.1.6 (22 January 2004) * Added a function option "dummy()" which means "no options". This simplifies the implementation of symbolic functions which are not to be further evaluated. * Removed a bug in the numerical evaluation of Li() that caused the system to hang for certain parameter combinations. * Fixed a bug in the calculation of hash values for indices that could lead to wrong results or bogus error messages from simplify_indexed(). * Fixed a bug in the evaluation of harmonic polylogarithms for complex arguments with positive imaginary part. 1.1.5 (5 November 2003) * Harmonic polylogarithms now numerically evaluate for arbitrary arguments (parameter must still be positive integers). * The zeta function now can also be given a lst as a parameter in which case it becomes a multiple zeta value. The use of mZeta is deprecated. * The order of parameters for the multiple polylogarithm has been corrected. * Documentation for the nested sums functions zeta, harmonic polylog, multiple polylog, etc. has been added. 1.1.4 (17 October 2003) * Lists and matrices can now be initialized from comma-separated lists of expressions, like this: lst l; l = x, 2, y, x+y; matrix M(3, 3); M = x, y, 0, -y, x, 0, 0, 0, 1; This is both faster and produces much smaller code than the old constructors lst(ex, ex, ...) and matrix(unsigned, unsigned, lst), especially in the case of matrices, and is now the recommended way to create these objects. * The function mZeta now evaluates much faster for arbitrary parameters. The harmonic and multiple polylogarithms evaluate considerably faster and check for convergence. The order of parameters for the harmonic polylogarithm has been corrected. 1.1.3 (22 August 2003) * Added new symbolic functions for better integration with nestedsums: (multiple) polylogarithm Li(), Nielsen's generalized polylogarithm S(), harmonic polylogarithm H(), and multiple zeta value mZeta(). * New exhashmap template intended as a drop-in replacement for std::map using GiNaC's hashing algorithms. 1.1.2 (11 August 2003) * Fixed a bug in the unarchiving of sums and products: terms were not reordered in a canonical way. * Fixed a bug in normal()/numer_denom(): denominator was not made unit normal if it was a simple number. * Improved the speed of subs() in some cases. 1.1.1 (18 June 2003) * lst (and exprseq) provide iterators for read-only element access. For sequential access this is one order faster than using op(). * Implemented relational::subs() (this was done in 1.0.9 but inadvertently omitted from the 1.1 branch). * pole_error and do_taylor are available to library users. * Added on-line help and Tab-completion for print(), iprint(), print_latex() and print_csrc() in ginsh. 1.1.0 (3 April 2003) * Removed deprecated macros is_ex_a, is_ex_exactly_a and friends for good. * The scalar_products mechanism allows the specification of an index dimension. * Removed dirac_gamma6/7(). * Added ex::to_polynomial(). * subs() accepts an optional "options" argument. The option subs_option::subs_algebraic enables "smart" substitutions in products and powers. * Added stream manipulators "dflt", "latex", "python", "python_repr", "tree", "csrc", "csrc_float", "csrc_double", "csrc_cl_N", "index_dimensions" and "no_index_dimensions" to control the output format. Calling basic::print() directly is now deprecated. * Made the hashing more simple and efficient. * Caveats for class implementors: - basic::subs(): third argument changed from "bool" to "unsigned" - unarchiving constructor and basic::unarchive(): "const" removed from second argument - basic::let_op() should only be implemented if write access to subexpressions is desired - simplify_ncmul() renamed to eval_ncmul() - simplified_ncmul() renamed to hold_ncmul() - nonsimplified_ncmul() renamed to reeval_ncmul() 1.0.14 (1 March 2003) * Improved the C-source output: complex numbers are printed correctly (using the STL complex<> template or cln::complex()), rational numbers use cl_RA() in the CLN output, and small integers are printed in a more compact format (e.g. "2.0" instead of "2.0000000e+00"). * function_options::set_return_type() and function_options::do_not_evalf_params() now actually work. 1.0.13 (27 January 2003) * Contracting epsilon tensors with Euclidean indices now works. * Improved dummy index symmetrization in sums. * Added dirac_gammaL/R(), which can be used instead of dirac_gamma6/7() but are single objects, to allow for a more compact notation of Dirac strings. * Powers with negative numeric exponents are printed as fractions in the LaTeX output. * Added symbolic_matrix() for the convenient creation of matrices filled with symbols. * Added collect_common_factors() which collects common factors from the terms of sums. * simplify_indexed() converts "gamma~mu*p.mu" to "p\". 1.0.12 (30 October 2002) * Fixed a bug in power::expand() that could produce invalid expressions. * The input parser no longer ignores extra data following accepted input. * Improved the CLN C-source output (integers are printed as integers, and floating point numbers include the precision). * Fixed a problem in the LaTeX-output of negative fractions. * Added print_latex() and print_csrc() to ginsh. * The sprem() function is now public. 1.0.11 (18 September 2002) * Fixed a possible memory corruption in contractions of indexed objects with delta or metric tensors. * Computing the derivative of a power series object with respect to a symbol that is not the expansion variable now works correctly. * Several bugfixes in code generation. 1.0.10 (24 July 2002) * Powers of indexed objects are now parenthesized correctly in LaTeX output. * Input parser handles indices (they have to be specified in the same list as the symbols). * Added some limited support for subspaces in the idx and tensor classes. * Fixed a bug in canonicalize() (antisymmetric canonicalization of an already sorted list containing two or more equal objects failed to return 0). 1.0.9 (11 June 2002) * simplify_indexed() now raises/lowers dummy indices to canonicalize the index variance. This allows some simplifications that weren't possible before, like eps~a.b~c~d*X.a*X~b -> 0 and X.a~a-X~a.a -> 0. * Implemented relational::subs(). * Fixed bug in simplify_ncmul() for clifford objects. 1.0.8 (31 March 2002) * Improvements in memory usage of the expand() methods. 1.0.7 (18 March 2002) * Fixed LaTeX output of indexed and matrix objects. * Fixed matrix::pow(n) for n==0 and added helper functions to create unit matrices "ex unit_matrix(unsigned, unsigned)". 1.0.6 (4 March 2002) * "(x+1).subs(x==x-1)" now returns the correct result "x" instead of "x-1". 1.0.5 (27 January 2002) * (l)degree(s), coeff(s, n) and collect(s) were extended to accept expressions of any class (except add/mul/ncmul/numeric) for "s". They should even work if "s" is a "power" object, as long as the exponent is non-integer, but with some limitations. For example, you can "collect(a*2^x+b*2^x, 2^x)" to get "(a+b)*2^x", but "degree(2^(3*x), 2^x)" yields 0 instead of 3). * Fixed a small output bug. 1.0.4 (24 January 2002) * Speedup in expand(). * Faster Bernoulli numbers (Markus Nullmeier). * Some minor bugfixes and documentation updates. 1.0.3 (21 December 2001) * Fixed a bug where quo() would call vector::reserve() with a negative argument. * Fix several bugs in code generation. 1.0.2 (19 December 2001) * Input parser recognizes "sqrt()", which is also used in the output. * divide(a,b,q) only modifies q if the division succeeds; also, divide(a,b,a) works now. * Fixed small bug in dummy index renaming which could cause it to not recognize renamable indices in some cases. * power::degree() and power::ldegree() throw an exception when encountering a non-integer exponent. * Add output-support for Python bindings. 1.0.1 (22 November 2001) * Function sqrfree() handles a few more cases now. * Class relational has real canonical ordering now. * Handle obscene libreadline version numbers when building ginsh. 1.0.0 (6 November 2001) * Some internal reorganization resulting in a general speed-up. * The last 3 evaluated expressions in ginsh are now referred to with the tokens '%', '%%' and '%%%'. The old '"', '""' and '"""' remain for compatibility but may be removed in a future version of GiNaC. 0.9.4 (20 September 2001) * Functions have better support for external scripting languages. * Interface cleanups and bugfixes. * Fix silly bug in evalf() that prevented things like 2^Pi being computed. 0.9.3 (16 August 2001) * series expansion now much more consistent for small order expansion. * lsolve() accepts algorithmic hint as parameter. 0.9.2 (31 July 2001) * Epsilon tensor is more functional. * simplify_indexed() is better at detecting expressions that vanish for symmetry reasons. * Several little bugfixes and consistency enhancements. 0.9.1 (27 June 2001) * Ctors of class numeric are not explicit any more. All built-in callers for pseudofunctions are now templated and default to ex arguments which relaxes the need for explicit ctors. * New functions/methods: - find() - remove_first(), remove_last(), sort() and unique() for lists - symmetrize_cyclic() - decomp_rational() * Instead of just totally symmetric or antisymmetric, complex symmetries can now be defined for indexed objects. Symmetries are described by a tree of "symmetry" objects that is constructed with the sy_none(), sy_symm(), sy_anti() and sy_cycl() functions. The symmetry of a function with respect to its arguments can also be defined (this is currently only used for the Beta function). * Generalized map() to take a function object instead of a function pointer. This allows passing an arbitrary number of additional state to the function being called. * color_trace(), dirac_trace(), diff(), expand(), evalf() and normal() work better with container classes, e.g. using color_trace() on a relation will take the trace on both sides, using diff() on a matrix differentiates every element etc. * diff() works properly with non-commutative products and indexed objects. * New option flag "expand_function_args" for expand(). * Supplement some (now deprecated) macros by inlined template functions: - is_of_type(foo, type) -> is_a(foo) - is_ex_of_type(foo, type) -> is_a(foo) - is_exactly_of_type(foo, type) -> is_exactly_a(foo) - is_ex_exactly_of_type(foo, type) -> is_exactly_a(foo) - ex_to_foobar(baz) -> ex_to(baz) * rem(c, p[x], x) (c: numeric, p[x]: polynomial) erroneously returned p[x] instead of c. * Small bugfixes in pattern matching. * Updated libtool to version 1.4. 0.9.0 (7 June 2001) * In the output and in ginsh, lists are now delimited by { } braces, and matrices are delimited by single [ ] brackets. * simplify_indexed() renames dummy indices so, e.g., "a.i*a.i+a.j*a.j" gets simplified to "2*a.i*a.i" (or "2*a.j*a.j"). * New functions/methods: - canonicalize_clifford() (helpful when comparing expressions containing Dirac matrices) - symmetrize() and antisymmetrize() - numer_denom() (return numerator and denominator in one call) - map() (apply function to subexpressions) - evalm() (evaluate sums, products and integer powers of matrices) * Added a new function match() for performing pattern matching. subs() and has() also accept patterns as arguments. A pattern can be any expression, optionally containing wildcard objects. These are constructed with the call "wild()" and are denoted as "$0", "$1" etc. in the output and in ginsh. * Positive integer powers of non-commutative expressions (except matrices) are automatically expanded. * Removed cint subdirectory, ginaccint is a separate package now due to packaging considerations. * Several little bugfixes. 0.8.3 (11 May 2001) * color and clifford classes are functional and documented. * New "spinidx" class for dotted/undotted indices. * Predefined spinor metric tensor (created by spinor_metric()). * Symbols can have a LaTeX name, e.g. symbol s("s", "\\sigma"); * LaTeX output of indexed objects is much nicer. * Fixed some build problems (with recent libreadline). * Semantics of arithmetic operators now follows the C++ rules more strictly. 0.8.2 (24 April 2001) * degree(), ldegree(), coeff(), lcoeff(), tcoeff() and collect() work with non-symbols as the second argument in ginsh. * the argument to collect() can be a list of objects in which case the result is either a recursively collected polynomial, or a polynomial in a distributed form with terms like coeff*x1^e1*...*xn^en, as specified by the second argument to collect(). * Several bugfixes (including a nasty memory leak in .normal()). * class matrix: solve() doesn't call algorithms redundantly any more and inverse() falls back to solve() which works in more general cases. 0.8.1 (16 April 2001) * degree(), ldegree(), coeff(), lcoeff(), tcoeff() and collect() can now be used with constants, functions and indexed expressions as well, so you can use it to collect by powers of Pi or sin(x), or to find the coefficient of gamma~0. Limitations: - it only works with symbols, constants, functions and indexed expressions, trying to find the coefficient of, e.g., "x^2" or "x+y" won't work; - it does not know about dummy index summations; the coefficient of gamma~0 in p.mu*gamma~mu should be p.0 but is returned as 0; - using coeff(), tcoeff(), lcoeff() or collect() on elements of noncommutative products might return wrong or surprising results. * subs() no longer only substitutes symbols and indices but performs a more general "syntactic substitution", i.e. it substitutes whole objects in sub- expressions. You can subs((a+b)^2,a+b==3) and get 9, but subs(a+b+c,a+b==3) doesn't do anything. Limitations: - substituting numerics (subs(expr, 2==4)) will not replace then in all occurences; in general, you shouldn't substitute numerics, though. * Added preliminary (re)implementations of color and clifford classes. * simplify_indexed(): contraction of symmetric and antisymmetric tensors is zero. * Replaced the various print*() member functions by a single print() that takes a print_context object that determines the output formatting. This should make it easier to add more output types, such as LaTeX output, which is based on work by Stefan Weinzierl. * Added functions to retrieve the properties stored in archive objects outside of unarchive() (for printing or debugging purposes). * Some bugfixes (indexed objects, archive writing). * .collect() on non-polynomials is now algebraically correct. 0.8.0 (24 March 2001) * Complete revamp of indexed objects. Instead of multiple classes for indexed things and their indices there is now only one "indexed" class and two types of indices: "idx" for simple indices and "varidx" for indices with variance. There are predefined delta, epsilon and metric tensors, and a function simplify_indexed() that performs canonicalization and dummy index summations. Matrix objects can be indexed for doing simple linear algebra. * Added an option "expand_indexed" to expand() to perform expansion of indexed objects like (a+b).i -> a.i + b.i * Renamed get_indices() to get_free_indices(), which no longer returns dummy indices and checks the consistency of indices in sums. * sqrfree() factorization fixed and improved syntactically. * subs() works on matrices. * Matrices can be constructed from flat list of elements; diagonal matrices can be constructed from list of diagonal elements with diag_matrix(). * Fixed memory leak in expand(). * Operator% for objects of class ncmul has gone. Use operator* now for that case too, which is much more natural. 0.7.3 (28 February 2001) * Several bugfixes and minor performance tunings. * Added a section to the tutorial about adding new algebraic classes to GiNaC. * Closed many in-source documentation gaps. 0.7.2 (17 February 2001) * Several bugfixes in power series expansion, one of them critical. 0.7.1 (7 February 2001) * Fix problems with Cint that were caused by CLN's overloaded operator new. * Fix compilation errors with GCC3. * normal() handles large sums of fractions better and normalizes the exponent of power expressions. * expand() always expands the exponent and transforms x^(a+b) -> x^a*x^b. * Some bugfixes of series expansion around branch cuts of special functions. 0.7.0 (15 December 2000) * Requires CLN 1.1 now. Class numeric doesn't use an indirect pointer to the actual representation any more. This is a speedup. * mul::expand() was reengineered to not allocate excess temporary memory. * Non-integer powers of a symbol are treated as constants by (l)degree() and coeff(). Using these functions on an expression containing such powers used to fail with an internal error message. The side-effect is that collect() can be used on expressions which are not polynomials. * Added a man page for the ginac-config script. * Ctor of numeric from char* honors Digits. 0.6.4 (10 August 2000) * Complete revamp of methods in class matrix. Some redundant (and poor) implementations of elimination schemes were thrown out. The code is now highly orthogonal, more flexible and much more efficient. * Some long standing and quite nasty bugs were discovered and fixed in the following functions: add::normal(), heur_gcd(), sr_gcd() and Order_eval(). 0.6.3 (25 July 2000) * Derivatives are now assembled in a slightly different manner (i.e. they might 'look' different on first sight). Under certain circumstances this can result in a dramatic speedup because it gives hashing a better chance, especially when computing higher derivatives. * Some series expansions of built-in functions have been reengineered. * The algorithm for computing determinants can be chosen by the user. See ginac/flags.h and ginac/matrix.h. * The Dilogarithm (Li2) now has floating point evaluation, derivative and a proper series expansion. * Namespace 'std' cleanly disentangled, as demanded by ISO/EIC 14882-1998(E). * Some minor bugfixes, one major lsolve()-bugfix and documentation updates. 0.6.2 (21 June 2000) * ginaccint.bin is now launched by a binary program instead of by a scripts. This allows us to write #!-scripts. A small test suite for GiNaC-cint was added. * Several minor bugfixes. 0.6.1 (18 May 2000) * Cleanup in the interface to Cint. The required version is now Cint 5.14.38. * Several bugfixes in target install. 0.6.0 (11 May 2000) * IMPORTANT: Several interface changes make programs written with GiNaC much clearer but break compatibility with older versions: - f(x).series(x,p[,o]) -> f(x).series(x==p,o) - series(f(x),x,p[,o]) -> series(f(x),x==p,o) - gamma() -> tgamma() (The true Gamma function, there is now also log(tgamma()), called lgamma(), in accord with ISO/IEC 9899:1999.) - EulerGamma -> Euler * #include'ing ginac.h defines the preprocessor symbols GINACLIB_MAJOR_VERSION, GINACLIB_MINOR_VERSION, and GINACLIB_MICRO_VERSION with the respective GiNaC library version numbers. * Expressions can be constructed from strings like this: ex e("2*x+y", lst(x, y)); * ex::to_rational() provides a way to extend the domain of functions like gcd() and divide() that only work on polynomials or rational functions (the good old ex::subs() method reverses this process) * Calling diff() on a function that has no derivative defined returns the inert derivative function "Derivative". * Several new timings in the check target. Some of them may be rather rude at your machine, feel free to interrupt them. 0.5.4 (15 March 2000) * Some algorithms in class matrix (notably determinant) were replaced by less brain-dead ones and should now have much better performance. * Checks were completely reorganized and split up into three parts: a) exams (small regression tests with predefined input) b) checks (lenghty coherence checks with random input) c) timings (for coherence and crude benchmarking) * Behaviour of .evalf() was changed: it doesn't .evalf() any exponents. * Expanded expressions now remember they are expanded to prevent superfluous expansions. * Small bugfixes and improvements in the series expansion. 0.5.3 (23 February 2000) * A more flexible scheme for registering functions was implemented, allowing for remembering, too. * Some Bugfixes. 0.5.2 (16 February 2000) * Mainly fixes a bug in the packaging of release 0.5.1. 0.5.1 (14 February 2000) * Fixes a small number of bugs. 0.5.0 (7 February 2000) * Expressions can be written ("archived") to files and read therefrom. * Addition of GiNaC-cint, which lets you write complete programs in an interactive shell-like manner in your favoured programming language (i.e. C++). 0.4.1 (13 December 1999) * Series Expansion of Gamma function and some other trigonometric functions at their poles works now. * Many more evaluations of special functions at points where exact results exist. * info_flags::rational doesn't return true for complex extensions any more---use info_flags::crational for the old behaviour. info_flags::integer and -::cinteger work similarly, the same holds for types like info_flags::rational_polynomial. 0.4.0 (26 November 1999) * First public release. pynac-0.2.6/README000066400000000000000000000040101212114631200134750ustar00rootroot00000000000000Pynac -- "Python is Not a CAS" is a modified version of Ginac that replaces the depency of GiNaC on CLN by a dependency instead of Python. It is a lite version of GiNaC as well, not implementing all the features of the full GiNaC, and it is *only* meant to be used as a Python library. -- William Stein ORIGINAL README General Information =================== GiNaC (which stands for "GiNaC is Not a CAS" (computer algebra system)) is a C++ library for symbolic mathematical calculations. It is designed to allow the creation of integrated systems that embed symbolic manipulations together with more established areas of computer science (like computation-intense numeric applications, graphical interfaces, etc.) under one roof.
