in reply to Fast Fourier Transform in Multiple Dimensions

take a look at The Perl Data Language. last i looked it did lots of really fancy math stuff over *large* matrices of *many* dimensions.

The PDL concept is to give standard perl5 the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets which are the bread and butter of scientific computing. e.g. $a=$b+$c can add two 2048x2048 images in only a fraction of a second.
