Is the cuFFT a "in place" FFT?

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.
