Math::MatrixReal 2.03 (Default branch)

Math::MatrixReal is a Perl module for manipulating NxM real matrices. Some of the notable features are operator overloading, LR decomposition, eigenvalue/eigenvector algorithms for symmetric matrices, and export to Matlab/LaTeX/Yacas formats. License: Perl License Changes:
This release uses Module::Build, so Math::MatrixReal should in theory be able to compile on systems without make. A new concatenation operator ".", e.g. $c = $a . $b, concatenates two matrices side-by-side. The function assign_row has been added. The beginning of a test suite overhaul to convert to Test::More.

math::bigint::fastcalc

Math::BigInt::FastCalc(3perl)				 Perl Programmers Reference Guide			     Math::BigInt::FastCalc(3perl)

NAME

       Math::BigInt::FastCalc - Math::BigInt::Calc with some XS for more speed

SYNOPSIS

       Provides support for big integer calculations. Not intended to be used by other modules. Other modules which sport the same functions can
       also be used to support Math::BigInt, like Math::BigInt::GMP or Math::BigInt::Pari.

DESCRIPTION

       In order to allow for multiple big integer libraries, Math::BigInt was rewritten to use library modules for core math routines. Any module
       which follows the same API as this can be used instead by using the following:

	       use Math::BigInt lib => 'libname';

       'libname' is either the long name ('Math::BigInt::Pari'), or only the short version like 'Pari'. To use this library:

	       use Math::BigInt lib => 'FastCalc';

       Note that from Math::BigInt v1.76 onwards, FastCalc will be loaded automatically, if possible.

STORAGE

       FastCalc works exactly like Calc, in stores the numbers in decimal form, chopped into parts.

METHODS

       The following functions are now implemented in FastCalc.xs:

	       _is_odd	       _is_even        _is_one	       _is_zero
	       _is_two	       _is_ten
	       _zero	       _one	       _two	       _ten
	       _acmp	       _len
	       _inc	       _dec
	       __strip_zeros   _copy

       Original math code by Mark Biggar, rewritten by Tels <http://bloodgate.com/> in late 2000.  Separated from BigInt and shaped API with the
       help of John Peacock.

       Fixed, sped-up and enhanced by Tels http://bloodgate.com 2001-2003.  Further streamlining (api_version 1 etc.) by Tels 2004-2007.
