I am a bit struggling to find function that would allow me to perform Inverse Discrete Fourier transform. I am using Intel IPP 7.1.
I performed FFT operation with IPP_FFT_NODIV_BY_ANY parameter, ippsFFTFwd_CToC_64fc function, how can I inverse it?
there's FFTInv for inverse transformation. Here's the link for IPP 7.1 reference manual ( https://software.intel.com/sites/products/documentation/doclib/iss/2013/ipp/ipp_manual/ippi.pdf ). Please refer page 583 for FFTInv.
