You can use PDL::Matrix 
#!/usr/bin/perl -w
use strict;
use PDL::Matrix;

my $m = pdl [
         [1,2,3],
         [4,5,6],
         [7,8,9]
];

Which then also allows you to perform clean, fast math on them.
my $m = pdl [
         [1,2,3],
         [4,5,6],
         [7,8,9]
];

my $n = pdl [
         [1,0,0],
         [0,1,0],
         [0,0,1]
];

my $r = $m x $n;
