when i saw simonms great solution i was ashamed of my own. But since it was a little trouble for me and because of TMTOWTDI here my approach.

use strict;
use warnings;
use Data::Dumper;

my @erg;
my @all=(["what", "is", "the", "matrix"],["matrix", "reloaded", "is", 
+"no", "good"]); 
print "\n",Dumper(\@all);

for (my $i = 0; $i < @{$all[0]}; $i++) {
    for (my $j = 0; $j < @{$all[1]}; $j++) {
        $erg[0][$i] ||= sprintf "%u", ($all[0][$i] eq $all[1][$j]);
        $erg[1][$j] ||= sprintf "%u", ($all[0][$i] eq $all[1][$j]);
    }
}

print "\n",Dumper(\@erg);
