Hi, I would like to ask why there is no FFTW guru interface equivalent? It would be incredibly helpful to have such an option, e. g. when computing 1D fft in Y axis over 3D domain. Right now one has to implement a transpositions to get reasonable performance…
Would it be a big deal to implement it in cufft library natively? VkFFT library supports omiting certain dimensions plus allows to perform transformations over arbitrary number of dimensions that is a big advantage as well.
Thank you!
