17 Apr 2013 IM2GIF Converts a multiframe image to an animated GIF. Author: Oliver Woodford

Oliver, coll idea, but when I run the example I get the following error:

154 A = cat(4, A{:});
Error using cat
Dimensions of matrices being concatenated are not consistent.
Error in im2gif>imread_rgb (line 154)
A = cat(4, A{:});
Error in im2gif>parse_args (line 117)
A = imread_rgb(A);
Error in im2gif (line 44)
[A options] = parse_args(A, varargin{:});

Where in cat(4, A{:}); A is an array of 6-8 images (type uint8), this was in 13a

26 Feb 2013 Mandelbrot set, animated zoom output: avi or gif Author: Maxim Vedenyov

Works great, just be prepared to 1) Let it run for several minutes, enough time for roughly 600 images to be generated.. Just doing a few iterations still took a bit, as with any movie.

Also, note that you will probably need/want to change the compression settings, taking that part off completely is quick and dirty and makes for a large file size, but it also works virtually no matter what which is nice.
