How to show the result from FFT2D ?

[ORKATZ9090]

Hi,

I used this function on my project:

FFT2D(signal, NUM_ROWS, NUM_COLS, NUM_ROWS, NUM_COLS, 0, fftOut);

Now I want to show the result (fftOut) on picture.

for example (matlab code):

fftOut= fftshift(fft2(signal));

imagesc(abs(fftOut));

What should I do?

Thanks,

Or
