There may be issues for developers who will not know what inputParser class is being used by others.

Note that unlike Matlab, if no validator is given, anything is valid, so giving no validator to an Optional argument will not turn any string on the list of arguments to be considered a ParamValue key. Summary of important user-visible changes for general 1.3.0: ------------------------------------------------------------------- ** The following functions are new: majle ** The class `inputParser' class has been implemented with many methods. It attempts to be as compatible with Matlab as possible. However, since classdef is not yet implemented the syntax differs slightly. Unlike the Matlab implementation, this functions return the object. For example: obj.method (arguments) # matlab implementation obj = obj.method (arguments) # octave implementation The octave implementatino expands on the Matlab one as it has one more type of API, see `help @inputParser/addSwitch'. ** The function `unvech' accepts a new argument scale to calculate the upper triangular part of the matrix thus returning non-symmetric matrix. ** The function `parcellfun' had the random number generator modifed, a new option to set the verbosity level, and other bugs corrected. ** Package is no longer automatically loaded. general-2.1.2/inst/0000755000000000000000000000000014167071540012301 5ustar0000000000000000general-2.1.2/inst/@dict/0000755000000000000000000000000014167071540013324 5ustar0000000000000000general-2.1.2/inst/@dict/dict.m0000644000000000000000000001015114167071540014423 0ustar0000000000000000## Copyright (C) 2009 VZLU Prague, a.s., Czech Republic ## ## 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 3 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.

The table is ## created by extending row and column vectors to like dimensions. If ## the dimensions of input vectors are not commensurate an error will ## occur. Dimensions are commensurate if they have the same number of ## rows and columns, a single row and the same number of columns, or the ## same number of rows and a single column. In other words, vectors ## will only be extended along singleton dimensions. ## ## @noindent ## For example: ## ## @example ## @group ## [a, b] = tablify ([1 2; 3 4], 5) ## @result{} a = ## 1 2 ## 3 4 ## @result{} b = ## 5 5 ## 5 5 ## @end group ## @end example ## @example ## @group ## [a, b, c] = tablify (1, [1 2 3 4], [5;6;7]) ## @result{} a = ## 1 1 1 1 ## 1 1 1 1 ## 1 1 1 1 ## @result{} b = ## 1 2 3 4 ## 1 2 3 4 ## 1 2 3 4 ## @result{} c = ## 5 5 5 5 ## 6 6 6 6 ## 7 7 7 7 ## @end group ## @end example ## ## @noindent ## The following example attempts to expand vectors that do not have ## commensurate dimensions and will produce an error. ## ## @example ## @group ## tablify([1 2],[3 4 5]) ## @end group ## @end example ## ## @noindent ## Note that use of array operations and broadcasting is more efficient ## for many situations. ## ## @seealso {common_size} ## ## @end deftypefn ## Author: Robert T.
