This come up now and again and I believe there's several half-baked/started solutions out there by Cython users, but nothing that is standard or that I know is carried out to completion. I.e., you should ask on the cython-users list. It'd be good if somebody would compile a list of the efforts so far on the wiki as well... > b) What is the status of supporting multi-type Cython functions -- ala > C++ templates ? > This would be one of my top ranked favorites, since I like writing > simple algorithms (like computing certain statistics over a numpy > array), and have this support all of e.g. unit8, int32, unit16, > float32 and float64...

We take an approach different to C++ though. http://wiki.cython.org/enhancements/fusedtypes Dag Sverre _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
