Many IPP functions have special versions with the letter 'I' in the name, where outputs are returned in-place in the input vectors. This applies to the FFT functions, but somehow not for DFT. Can the DFT functions be used in-place by passing the same pointer for pSrc and pDst? For example, will this work with ippsDFTFwd_CToC_32fc or ippsDFTInv_CToC_64f and their inverses?
Conversions between Cartesian and polar representations are another good example where it would be highly desirable to do the conversion in-place instead of copying and potentially causing cache misses. Will ippsCartToPolar_64f work correctly if pSrcRe == pDstMagn and pSrcIm == pDstPhase? What about ippsPolarToCart_64f?
