The example of FFT in IPP9.0 (2016XE)

hi ,

I want to use FFT on the Xeon Phi ,but the MKL-FFT performance is not good.I want to try IPP ,but I can not find the FFT API in IPP guide .

And the path which the guide mentioned :<install_dir>/ipp/components  not exist .

What is more, I found the oldversion sample for IPP8.0 named ipp-examples/ipp_fft but the compile said these function has been removed .

So please help me to find the FFT example for IPP9.0 ,thank you very much!
