[Matplotlib-users] [Numpy-discussion] which fft I should use

This was seen on numpy-discussion. Is this the behavior implemented in
matplotlib/numerix/fft/__init__.py ?

Doesn't look like it to me ...

For maximum portability and speed, use numpy.dual.fft() and its friends. That
will use the optimized functions in scipy.fftpack if it is available and
numpy.fft otherwise.
