Ah, too much good stuff!

It seems that the transposition step is unnecessary for this algorithm, anyway, but that is a much better implementation, regardless, and I'll incorporate it for later use. Quite the performance jump that map() provides. Mmm, lispy goodness.

It might further be worthwhile to pass it on in the RT to the Math::Matrix maintainer as a performance patch, since that's where I took the original function from, also.

Thank you again, kind and knowledgeable good sir monk.
