This module is an extension to the Math::Symbolic module. A basic familiarity with that module is required. Math::SymbolicX::Inline allows easy creation of Perl functions from symbolic expressions in the context of Math::Symbolic. That means you can define arbitrary Math::Symbolic trees (including derivatives) and let this module compile them to package subroutines. WWW: http://search.cpan.org/dist/Math-SymbolicX-Inline/
