Why not use a hash? This is where they shine: 

## I don't know how you're getting values for $i, $j, $value
$hash{$i}{$j} = $value;

Update2: To print: 
foreach $i (keys %hash) {
   foreach $j (keys %{ $hash{$i} }) {
      print $i, $j, $hash{$i}{$j}, "\n";
   }
}

Hope this works for you.

Update1: If you insist on arrays, however, this will also work (but is more work): 

push @array, "$i:$j:$value";

## to print:
foreach (@array) {
   print join (' ', split ":");
}

[download]
@a=split??,'just lose the ego and get involved!';
for(split??,'afqtw{|~'){print $a[ord($_)-97]}
