Hello,

I would like to use the Fast Fourier Transform in my own code to find
frequency centers of some FIR filters :
I plan to make transform of this filters, get pixels with maximum magnitude,
and extract their frenquencies (~distance to the center). Am I right ?

The thing is I don't know how to call the IJ transform in my code and get
the result. Could you advise me ?

(Is there a simple way to obtain the frequency corresponding to a pixel in
the freq. domain ?).

Regards,

Pol
