Thanks for the confirmation; that's what I meant to say when I wrote
"postmultiplying the eigenvector by the original matrix."

Thanks, everyone, for this.

If I get a moment, would anyone object if I pick some of the best code,
add the eigenvalue calculation, and put it on the Wiki as a Saaty
framework in J?  I'd try to credit the right people with the code I
used; as it's a Wiki, anyone I missed could certainly make the
appropriate edits.

If anyone beats me to it, that's perfectly fine; I'm rather far behind
right now.
