    You can typically just do: 
    $a[$i][$j]=5;

    However if you want to do a foreach on one of the sets of elements it gets more complicated. 
    @array=(
    ["Homer","Marge","Bart","Lisa","Maggie"],
    ["Ned","Maude","Rod","Todd"]
);

foreach my $ref(@array){
    print "This family consists of: ";
    foreach(@$ref){
      print "$_ ";
    }
    print "\n";
}

    Declaring an Array Of Arrays: 
    @array = (
          ['red', 'white'],
          ['blue', 'green', 'yellow'],
          ['vortex', 'singularity']
         );


On the fly:

for $index (0..4)
{
    push @array, [1, 1, 1, 2];
}
