This is an example of how to create animations and animated GIFs in MATLAB®. In this example, we will animate the motion of a double-pendulum. We solve the ordinary differential equation using "ode45".
Read about the "getframe" and "imwrite" functions in the MATLAB documentation.

The example works as written in R2020a with no changes required.
@Jose: Is it possible that you need to clear your workspace before running or that you have a function that shadows rgb2ind? The frames that are being generated are 420 x 560.
Unable to perform assignment because the size of the left side is 840-by-1120 and the size of the right side is 945-by-1260.
Error in Animation (line 61)
[mov(:,:,1,id), map] = rgb2ind(f.cdata, 256, 'nodither');
This is error I get in matlab2020a
even with Jose replacment
In Matlab 2020a it doesn't work.
Solved by changing line 59 with:
% Preallocate data (for storing frame data)
mov = zeros(height*2, width*2, 1, length(T), 'uint8');
I liked the animation in the form of a gif. I intend to use this in my web site :). Thank you
