Math::MatrixReal is a nifty perl module for doing just about anything you could want with an NxN matrix, or vector of real numbers. Find Math::MatrixReal at: http://leto.net/code/Math-MatrixReal/

Provides the functionality for Jython that Numerical Python does for Python (CPython). As the Numerical Python documentation states, it is "…a collection of extension modules to provide high-performance multidimensional numeric arrays to the Python programming language." JNumeric provides the same … Continue reading →
