note barrachois I wrote a Vector.pm module when I was exploring how to do perl math with Inline::C, which might be a useful example for people thinking of going that route. <p> While I didn't try to put in more than the basics, it does let you create and work with big vectors of doubles, like this: <code> use Vector qw(vector); my $a = vector( size=>10000, first=>0.0, by=>0.01 ); my $b = sin($a); my $c = $a + $b; print $c->[200]; </code> You can find the source code, documentation, and a test suite at <a href="http://cs.marlboro.edu/code/perl/modules/Math/Vector/">http://cs.marlboro.edu/code/perl/modules/Math/Vector/</a> 284324 284324
