Hah, only the scientists who haven't heard of PDL
(http://pdl.perl.org).

    PDL (``Perl Data Language'') 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.

    PDL turns perl in to a free, array-oriented, numerical language
    similar to such commerical packages as 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 manipulate
    the whole image in a few seconds.

Mark.
