By the way, I should apologize for a comment that was inadvertently
rather curt. I simply meant to note that in py4science there's code
from several people, and the fft piece was written by Stefan when we
taught the workshop together.
But Andrew had no way to know that, since that code isn't individually
marked for authorship (there are acknowledgements at the start of the
main document). Sorry about that, mate.
Cheers,
