NArray, NImage, and FFTW would seem to be exactly what you're asking for. (Note that if you install narray from the freebsd port/package, it doesn't install nimage - you have to go in and make it by hand for some reason). -Dave -- work: dga / lcs.mit.edu me: dga / pobox.com MIT Laboratory for Computer Science http://www.angio.net/
