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]
