Matlab: Using imshow and mesh in the same plot

  1. Oct 3, 2011 #1
    Hi,
    I have written a piece of code to plot a greyscale image using imshow and a mesh plot using mesh in the same plot (the graphs are subplots in the smae figure. My problem is that when I use imshow the meshplot turns to greyscale rather than colour, and I can't worj out how to have one plot as greyscale and the other as colour.

    My code is below if this helps;

    %Script to show diffraction grating
    clear all

    M=dlmread('testslit5.txt','\t');

    subplot(2,1,1),imshow(M);
    title('Diffraction grating');

    Mtransform=fft2(M);
    Mtransform=fftshift(Mtransform);
    N=max(max(Mtransform));
    Mtransform=Mtransform/N;

    subplot(2,2,3),mesh(abs(Mtransform));
    title('Diffraction grating diffraction pattern (intensity)');
    subplot(2,2,4),mesh(angle(Mtransform));
    title('Diffraction grating diffraction pattern (phase)');

    Thanks in advance
