Thanks for the thoughtful reply Travis. I see I will just have to get used to using code such as M[(P==Z).A.ravel(),:], which I can live with. Your comments helped put this in perspective for me. By the way, is there a web site that lists all the current modules (as does http://www.scipy.org/doc/api_docs/scipy.html)?
