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.
