JNumeric: Numerical Python for Jython JNumeric 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 functionality as the core of Numeric module and aims to provide all of the standard extensions to Numeric module (FFT, LinearAlgebra, RandomArray). In effect, Numerical Python is a free alternative to commercial solutions such as Matlab with the added bonus of the Python language which can be argue to be much better than what can be found in most commercial solution. You have to try Python to understand! (Source: http://freecode.com/)
