Hi dws-- I commented out individual snippets of this code. The slowest thing by far is the matrix building line, $matrix$j->$i = $hash{$key}; Also somewhat slow is the looping through the hash. The loading of the data is completely quick. So: does anyone know a better way to load values more quickly into a large matrix?
