Well in the meantime I learned several things; for my particular problem matlib.repmat is better suited than kron anyway (note that repmat isn't mentioned yet in the numpy book), and "zero-length dimensions" may not be the accurate term in numpy-speak (would zero-length axis be ok?), however I still haven't learned the reason for kron's partial limitation described above... any insights on this? thanks again, sven _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
