(A rank-0 transform is equivalent to a 1D transform of size 1, which. just copies the input into the output.) Specifying the same location for the input and output makes the transpose in-place.

WebThe manual of fftw_plan_guru_dft says: These two functions plan a complex-data, multi-dimensional DFT for the interleaved and split format, respectively. Transform dimensions … WebEDIT: @wakjah 's reply to this answer is accurate: FFTW does support split real and imaginary memory storage via its Guru interface. My claim about hacking is thus not accurate but can very well apply if FFTW's Guru interface is not used - which is the case by default, so beware still! First, sorry for being a year late.

WebThe guru interface supports two representations of complex numbers, which we call the interleaved and the split format. The interleavedformat is the same one used by the basic and advanced interfaces, and it is documented in Complex numbers. In the interleaved format, you provide pointers to the real part of a
