Record Animation for Playback

These examples show how to record animations as movies that you can replay.

Record and Play Back Movie

Create a series of plots within a loop and capture each plot as a frame. Ensure the axis limits stay constant by setting them each time through the loop. Store the frames in M.

for k = 1:16
	plot(fft(eye(k+16)))
	axis([-1 1 -1 1])
	M(k) = getframe;
end

Play back the movie five times using the movie function.

figure
movie(M,5)

Capture Entire Figure for Movie

Include a slider on the left side of the figure. Capture the entire figure window by specifying the figure as an input argument to the getframe function.

figure
u = uicontrol('Style','slider','Position',[10 50 20 340],...
    'Min',1,'Max',16,'Value',1);
for k = 1:16
    plot(fft(eye(k+16)))
    axis([-1 1 -1 1])
    u.Value = k;
    M(k) = getframe(gcf);
end

Play back the movie fives times. Movies play back within the current axes. Create a new figure and an axes to fill the figure window so that the movie looks like the original animation.

figure
axes('Position',[0 0 1 1])
movie(M,5)
