persistent fft

fft via a radix2 algorithm

You are now following this Submission

fft via a radix2 algorithm that "recurses" by calling matlab's fft. Rather quick on repeated calls for fft's of the same size, due to persistent variables, but still a little bit slower than matlab's builtin fft.

There is no advantage to using this code over the builtin fft.

Handles complex, vector inputs.
