How can i build the amplitude and phase image from a series of images

I need to build the amplitude and phase image from a series of images x=b(:,:,1); t = 0:1/100:10-1/100; % Time vector y = fft(x); % Compute DFT of x m = abs(y); % Magnitude p = unwrap(angle(y)); % Phase

 f = (0:length(y)-1)*100/length(y);        % Frequency vector
 subplot(2,1,1)
plot(f,m)
 title('Magnitude')
 ax = gca;
 ax.XTick = [15 40 60 85];
subplot(2,1,2)
 plot(f,p*180/pi)
 title('Phase')
 ax = gca;
 n = length(y)
 ax.XTick = [15 40 60 85];
 y = fft(x,n);
t = 0:1/255:1;
x = sin(2*pi*120*t); 
y = real(ifft(fft(x)));
 i obtined this result 'untitled.fig'  but i need to build this image

please help me to found this result
