When I use the DSPLib function, the forward FFT function DSPF_sp_fftSPxSP has been realized correctly with the same result with MATLAB. But the inverse FFT is wrong, even with the demenstration DSPF_sp_ifftSPxSP_d, the realted input, output and other parameters are set with the same form with forward fft, and the twiddle factor is generated with the given function tw_gen(float * w, int n) in DSPF_sp_ifftSPxSP_d. I want to ask about wheter there is somthing different with the forward fft needed to noticed. Thank you!!
