FFT v9.0 C-model-->Issue in cascading FFTs.

Hi,

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. 

 

Regards,

sarath
