Just my 2 cents on the issue of replacing Numeric by Numarray: I was under the impression that Numarray was intended to be a replacement for Numeric, also as a building block for larger packages such as SciPy. Was Numarray not intended to be an "improved Numeric" in the first place? I chose to develop for Numarray rather than Numeric because of its improvements, under the assumption that eventually my code would also become available to the users of such packages as SciPy. (I wrote the nd_image extension that is now distributed with Numarray. I also contributed some improvements to RandomArray extension that are not in the Numeric version.) I believe that it would be a bad situation if the numerical python community would be split among two different array packages. (I think Paul Dubois expressed a similar sentiment on comp.lang.python). Supporting code for two incompatible packages would be a pain (I am personally not willing to do that). Not being able to use modules designed for one package in the other would be disappointing for many people, I think... If I understood well, the only issue with Numarray seems to be that the speed for handling small arrays is too low. So would it not be more efficient to focus on that problem rather than throwing away all the excellent work that has been done already on Numarray? Best regards, Peter -- Dr. Peter J.
