For many operations on noncontiguous arrays, Numeric makes a contiguous temporary copy before performing the operation, so if you're going to do more than one thing with a noncontiguous array, you should make a copy yourself. Don't know if numarray works the same way, but I'd guess that it would. Warren Focke ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
