ippsFFTFwd_CToC_32fc(pSrc,pDst,pFFTSpec,pFFTWorkBuf);

[Alex_K_7]

 For a basis I followed an example from this links:

http://software.intel.com/en-us/articles/how-to-use-intel-ipp-s-1d-fourier-transform-functions ;

I don't understand function   ippsFFTFwd_CToC_32fc(pSrc,pDst,pFFTSpec,pFFTWorkBuf); To make a FFT it is necessary to have values of any signal.

Help me pls.

Hi Alex,

be more specific (and don't use Ru comments in the posted code) - I don't understand your question. Put "any signal" to pSrc and you'll have transformed signal in pDst. What is the problem?
