Yes I did, check the attachment of my previous message for a python module to time the three,
Sorry about that, I don't notice that.
with completely different results from yours (I'm using Numeric).
I ran it and got similar results to mine. Frankly, for the size problems I'm dealing with, they are all about the same, except for under Numarray, where mine is fastest, your second, and Robert third -- by a wide margin!
Another reason I'm glad numpy is built on the Numeric code:
Using numarray My way took: 0.394555 seconds Robert's way took: 20.590545 seconds Rob's way took: 4.802346 seconds Number of X: 201 Number of Y: 241
Using Numeric My way took: 0.593319 seconds Robert's way took: 0.523235 seconds Rob's way took: 0.579756 seconds
Robert's way has a pretty decent edge under numpy:
Using numpy My way took: 0.686741 seconds Robert's way took: 0.357887 seconds Rob's way took: 0.796977 seconds
And I'm using time(), rather than clock() now, though it dint' really change anything. I suppose I should figure out timeit.py
Thanks for all your help on this,
-Chris
