If you know the formula (i.e., how to create the result by hand) you shouldn't have any difficulty in creating the subroutine yourself. What difficulty are you having with it?

As I see it, you'd start with something like:

sub Normalize {
   my $v = shift;
   my $vSquared = InProduct($v, $v);
   my $divisor = ... square root of  sum of components of vSquared ...
   my $newVec1 = ... vector created by components of v divided by posi
+tive divisor ...
   my $newVec2 = ... vector created by componets of v divided by negat
+ive divisor ...
   .... whatever else is needed ...
   return $stuff;
}

my @dipoleMomentVectors = Normalize($dipoleMoment);
