HI, Following code generates 3 subplots for 3 different value of ik in 1 window , since the loop iterates ik= 1:3. I need to modify this peice of code to generate a single plot for variable Sum merging all three value of ik into one plot

     Sum=0;
 for ik=1:3
    Image = S(ik)*((abs(Phi(:,:,ik)).^2)); 
    Sum= Sum+Image;
    subplot(3,1,ik);
    mesh(fftshift(X),fftshift(Y), fftshift(abs(Sum)),'FaceColor','flat'); view(0,90);
    xlim([-2,2]); ylim([-2,2]);
    axis square;
    xlabel('f_x');
    ylabel('f_y');
    title(sprintf('Kernel %d Mag',ik));
end

Hi Sagar,

I understand that you want to create a single plot for variable Sum merging all values of ik instead of a subplot for each possible ik.

You can use the command 'hold on' and 'hold off' instead of 'subplot' which retains plots in the current axes so that new plots added to the axes do not delete existing plots.

Here is the documentation link for hold

Hope this helps you.
