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.
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:
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];
You can find
