Can anyone provide a one-paragraph description of what numarray does that gives it better large-array performance than Numeric?
It has two aspects: one is speed, but for us it was more about memory.
Thanks for the summary, I have a better idea of the issues now. It doesn't look, to my untrained eyes, like any of these are contrary to small array performance, so I'm hopeful that the grand convergence can occur. -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
Can anyone find the missing mail from the thread below? I have Chris's original question and his thanks for the reply, but not Perry's reply. I can't seem to conjure up the right incantations to get Google to find it, and I am also quite interested in the answer. Could someone forward me Perry's email or point me to somewhere that it's archived, please and thank you? Chris Perkins On Wed, 19 Jan 2005 09:29:51 -0800, Chris Barker <Chris.Barker@noaa.gov> wrote:
