the problem is it is taking s value only as p i.e 512 i wanted to run for the range s=1 to 512, so as to get q as 512 values each for which of s value . I(:,:,1) r channel for lena image

ya=((1+(I(:,:,1).^2)));
  p=512;
    for s=1:p
               Ya=ya.^(s);
               k= fft2(allpixel);
               f=abs(fft2(allpixel)).^2;
               q=Ya.*f;
               imshow(q,[])
                 total=(1/2*pi).*sum(sum(q));
      end
