I have a matrix of data 512 * 256 i am taking a 512 point FFT in column direction after that i am taking a 256 point FFT in row direction . Result of 2nd FFT is mismatching with reference results (i have correct reference results with me). I am using FFT v9.0 c model .
I would like to know can i feed output of one fft to another FFT directly ?
Do i need to do any kind of processing before feeding output of one fft to another ?
Kindly give me a reply.
