More on CUFFT<br />
For 2D and 3D transforms, CUFFT uses row-major<br />
order<br />
CUFFT performs un-normalized transforms<br />
IFFT(FFT(A)) = length(A)*A<br />
CUFFT modeled after FFTW<br />
Based on plans used to specify optimal configuration<br />
for a particular sized FFT<br />
Once a plan is created it can be reused (to avoid<br />
recomputing the optimal configuration)<br />
