Hi etheral,
A slightly less involved solution may be trying Math::Matrix instead.
#!/perl
use strict;
use warnings;
use diagnostics;
use Math::Matrix;
my $x = new Math::Matrix (
[ 3, 2, 3 ],
[ 5, 9, 8 ],
);
my $y = new Math::Matrix (
[ 4, 7 ],
[ 9, 3 ],
[ 8, 1 ],
);
my $z = $x->multiply($y);
print "$z\n";
__END__
