First you must recognize that there is no such thing as a
multidimensional array. It is really an array that holds arrayrefs as
values. When you successfully wrap your head around that concept you
will see that there is no difference between "normal" arrays and
multidimensional arrays.
<example>
#!/usr/bin/perl
use strict;
my @LoL = (
[ 1, 0, 0 ],
[ 0, 0, 1 ]
);
for my $x (0..$#LoL) {
for my $y (0..$#{$LoL[$x]}) {
print "$LoL[$x][$y] ";
}
print "\n";
}
</example>
