pdl - 1:2.081-2 main

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. The idea
is to turn perl in to a free, array-oriented, numerical language
in the same sense as commercial packages like IDL and MatLab. One
can write simple perl expressions to manipulate entire numerical arrays
all at once. For example, using PDL the perl variable $a can hold a
1024x1024 floating point image, it only takes 4Mb of memory to store
it and expressions like $a=sqrt($a)+2 would manipulate the whole image
in a few seconds.

A simple interactive shell (perldl) is provided for command line use
together with a module (PDL) for use in perl scripts.
