Is the cuFFT a “in place” FFT
It is if idata = odata! ;) It’s detailed in the manual.
Anyone who has implemented a fftshift-function as the one in Matlab? Need one for 3D…
If a “In Place FFT” faster as a “Not In Place FFT” ?
If a Real to Complex FFT faster as a Complex to Complex FFT?
From the “Accuracy and Performance” section of the CUFFT Library manual (see the link in my previous post):
I didn’t notice an answer to this one in my quick scan of the documentation, but it may be there.
