MATLAB: How to crate a video of multiple surf plots

plotsurfvideo

I am running a code which produces a surf plot for every step of the loop. I want to create a video of the all these surf plots produced in each step. How can I do that?

Best Answer

h = figure;
axis tight manual % this ensures that getframe() returns a consistent size
filename = 'test.gif';
[X,Y,Z] = peaks(100) ;
for n = 1:50
    % Draw plot for y = x.^n
    surf(X,Y,randsample(10,1)*Z) ;
    zlim([-100 100])
    shading interp
    drawnow
    % Capture the plot as an image
    frame = getframe(h);
    im = frame2im(frame);
    [imind,cm] = rgb2ind(im,256);
    % Write to the GIF File
    if n == 1
        imwrite(imind,cm,filename,'gif', 'Loopcount',inf);
    else
        imwrite(imind,cm,filename,'gif','WriteMode','append');
    end
end
