If you want to make an animated GIF from matlab its a pain. But there is a way to do it. With this function you can make your movie in for loop, and then get each frame with getframe. Then send that through frames2gif and you'll get an animated gif out. The function is pretty simple, it's just a bit tricky.

fh = figure();
for i = 1:num_frames
% Draw a frame on the figure.
frames(i) = getframe(fh);
end
frames2gif('my_movie.gif', frames, 'DelayTime', 0, 'LoopCount', Inf); % For a looping gif.
