Thanks for the explanation. I'm puzzled by the naming choice, however. Standard best practice in writing software is to give understandable names, to improve readability and code maintenance. Obscure abbreviations like "pinv" pretty much went out with the FORTRAN 9-character limit for variable names. It's very unusual to see them in new software nowadays, and it always looks unprofessional to me. I understand that for interactive use, short names are more convenient; but shouldn't they be available aliases to the more general names? Since numpy is primarily a software library, I wouldn't expect it to sacrifice a standard best-practice in order to make things more convenient for interactive use. If the concern is for for matlab compatibility, maybe a synonym module numpy.as_matlab could define all the synonyms, that matlab users could then use? That would make more sense to me than inflicting obscure matlab names on the rest of the user community. Vicki Laidler > > Victoria G.
