I'm curious as to the current state of numarray vs. Numeric performance. My code is a mix at the moment: - Numeric: coordinate conversion code that was written before numarray was very solid and makes heavy use of small matrices. - numarray: some image processing stuff that uses PyFits (which uses numarray).

I'd like to settle on one package. At one time numarray was at a clear disadvantage for small arrays, but was wondering if that was still true.

It is still true that numarray is at a disadvantage for small arrays.

Any advice?

I don't think there is a single array package that provides both PyFITS and good small array performance. Consider porting your conversion code to numarray and then profiling to get a better idea of the overall performance costs of your application. If you find a specific hot spot we can try to address it. Regards, Todd
