Hi folks, I've got a project that uses Numeric arrays a fair bit. Unfortunately, I have a fair number of users that would like to be able to use it without Numeric (frankly I don't get it. It's a wxPython widget, and once you've installed wxPython, Numeric should not be a show stopper, but whatever). I though one way to accommodate this was to create a pure python Numeric-lite package, that contained the functionality need for my app, and was written in pure python. A side benefit of this is that it would be an easy way to see how much a performance gain Numeric gives me. Frankly, I don't really care that much, I like using Numeric operations for the syntactical advantages, aside from performance issues. Anyway, I recall a while back a couple folks did some testing with Psyco and a pure-python implementation of a small fraction of Numeric functionality. I'd love to see that code if it's still around. Or if any of you has done something similar, I'd love to see that too. -thanks, Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov
