OK, this is what I had found. > From a computational point of view, this isn't particularly a problem: > the intermediate array cannot be large enough to be a problem without > the slices along at least one axis being large enough that for loop > overhead is pretty minor. OK, I here what you are saying: the loop is not costing me that much, because anyhow the operation would be slow, and the overhead is small. I have just grown to find that vector operations are easier to read than loops (to a trained eye). Thank for confirming my findings, Gaël _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
