How can I import previously created math functions?

bladx has asked for the wisdom of the Perl Monks concerning the following question:

Are there other modules other than the basic MATH module(s) that contain libraries of common equations, as to alleviate writing out each individual equation?

PDL is an extension which gives high speed matrix operations, and more. It has been used a lot for graphics and for scientific computing. Gsl is a yet-incomplete extension which uses the Gnu Scientific Library (GSL). It is a wip, only in version 0.03. So far it has bindings for calculating special functions. I was unable to install it due to hardcoded paths which disagreed with my gsl tree.	[reply]

PDL gained (some) GSL support with 2.003, in 1999. There is still only a subset of GSL with PDL bindings, but it is a large and useful subset.	[reply]

The amazing Inline module offers help here, too. Not all <math.h> functions are available in Perl (even if you use POSIX;). Here's how to print some erf() values, for instance (a function almost certainly available in your maths library): `perl -le 'use Inline C => q{ double erf(double); }, ENABLE => "AUTOWRA +P"; print "$_ ",erf($_) for (0..5)'` [download] You can of course write it into your modules, and use it to access you own libraries. Other C wrapping options are XS (of course) and Swig.	[reply] [d/l]

The Math::Cephes module contains an interface to math functions of Stephen Moshier's cephes math library. Interfaces are also included to handle some common polynomial, matrix, fraction, and complex number operations.	[reply]
