fftshift is a Matlab function; there is no such function in the FFTW
library. Of course, it's not hard to write such a function (at least
for even sizes), and see also question 3.10 in the FFTW FAQ
(fftw.org/faq) for a different trick.

Hi
Need to do fftshift in 3 dimensions using fftw library
but can't find it. Does anyone know if there is a function
for this in the above library ?
Thanks in advance
