Thanks. How do I generalize this to two (or more) dimensions?

For example, the code below selects a subset of the first index (which runs from 0-5).

How do I modify it so it also selects a subset of the second index (which runs from 0-3)?

use strict;
use warnings;

use Data::Dumper qw(Dumper);

my $matrix;
my @matrix;

$matrix[0][0] = 00;
$matrix[1][0] = 10;
$matrix[2][0] = 20;
$matrix[3][0] = 30;
$matrix[4][0] = 40;
$matrix[5][0] = 50;

$matrix[0][1] = 01;
$matrix[1][1] = 11;
$matrix[2][1] = 21;
$matrix[3][1] = 31;
$matrix[4][1] = 41;
$matrix[5][1] = 51;

$matrix[0][2] = 02;
$matrix[1][2] = 12;
$matrix[2][2] = 22;
$matrix[3][2] = 32;
$matrix[4][2] = 42;
$matrix[5][2] = 52;
$matrix[0][3] = 03;

$matrix[1][3] = 13;
$matrix[2][3] = 23;
$matrix[3][3] = 33;
$matrix[4][3] = 43;
$matrix[5][3] = 53;

print Dumper \@matrix;

my @matrix2 = @matrix[0, 2];
print Dumper \@matrix2;

my @matrix3 = @matrix[0, 1, 5];
print Dumper \@matrix3;
