PDL

PDL gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data arrays which are the bread and butter of scientific computing.

PDL turns Perl in to a free, array-oriented, numerical language similar to such commerical packages as IDL and MatLab. One can write simple Perl expressions to manipulate entire numerical arrays all at once.

A simple interactive shell (perldl) is provided for use from the command line and a module (PDL) for use in Perl scripts.

The PDL distribution for Perl is free software and provides extensive numerical and semi-numerical functionality with support for two- and three-dimensional visualisation as well as a variety of I/O formats. The goal is to allow PDL to interact with a variety of external numerical packages, graphics and visualisation systems. Easy interfacing to such systems is one of the core design features of PDL.
