PDL, i have never heard about that and from glancing at the linked page i also can't figure out how it would help me.
You seem to be doing quite a lot of array calculations, and if I understand it correctly, that's what PDL (pdl.perl.org) is particularly good at:
PDL ("Perl Data Language") gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data arrays.
Please do check out the demos, screenshots and success stories.
