in reply to The problem of getting the unit vector "Undefined subroutine &main::Normalize"

A couple of minor coding related comments:

for (my $frame = 201; $frame <= 300; $frame++)

is better written:

for my $frame (201 .. 300)

Perl treats $a and $b as somewhat special variables (see sort) so it's usually best to avoid them unless the sort context version of the variables is what you really mean.

Premature optimization is the root of all job security
