For a similarity matrix, then Algorithm::NeedlemanWunsch is probably what you are looking for. See also: Text::WagnerFischer String::LCSS_XS	[reply]

Maybe something like this? Assumes symmetry (d(x, y) = d(y, x)). `my @sim; my @words = ...; for my $i (0 .. $#words) { for my $j ( ($i+1) .. $#words) { $sim[$i][$j] = similarity( $words[$i], $words[$j]) $sim[$j][$i] = $sim[$i][$j]; } } sub similarity { my ( $w1, $w2 ) = @_; my $sim = 1; # calc simularity return sim; }` [download]	[reply] [d/l]
