Hi Nadav, What do you mean by "empty", zero length? ==> YES: Something like: fft(array([])) Todd

Looks like a bug in the fft wrapper code to me. I can either make it a no-op or make it raise an exception. I'm leaning towards the former... do you care which? Todd

Returning zero length array with the appropriate type code seems to be fine (and consistent). Nadav. Todd Miller wrote:
