What happened to the in-place functions of the real-to-complex DFTs in IPPS?
The documentations mentions additional functions with only one argument (pSrcDst) for in-place calculation. However, the header provides such in-place functions only for FFT and not for DFT transformations.
Calling ippsDFTFwd_RToCCS_32f(in, out, spec, buf) with in==out results in an error: ippStsContextMatchErr Invalid context structure.
Any thoughts? Thanks!

Hi Sonke,
I guess, you are looking for IPP 9.0 (or from IPS 2016 ) documentation, right? Are you working windows or linux?
Regarding in-place functions, we had planed to deprecate all of them in early version as in most of case, the in=out can solve the problem. But later we restore some of them as requested and widely used, like ippsFFT.
Do you have a small test case, so I can debug right away?
Best Regards,
Ying
