Starting in MATLAB R2022a, use the append option in exportgraphics to create GIF files from animated axes, figures, or other visualizations.

This basic template contains just two steps:

% 1. Create the initial image file
gifFile = 'myAnimation.gif';
exportgraphics(obj, gifFile);

% 2. Within a loop, append the gif image
for i = 1:20

      %   %   %   %   %   %    % 
      % Update the figure/axes %
      %   %   %   %   %   %    % 
      exportgraphics(obj, gifFile, Append=true);
  end

Note, exportgraphics will not capture UI components such as buttons and knobs and requires constant axis limits.

To create animations of images or more elaborate graphics, learn how to use imwrite to create animated GIFs .

How should I set the frame rate of a gif generated through exportgraphics?

exportgraphics does not currently have an option to control frame rate of GIFs.
The documentation for exportgraphics > Append argument suggests to use imwrite for more elaborate graphics. Also see Write Animated GIF.

Can a gif file be put into an Answers posting, and show up as animated?

A produced gif file can be uploaded and displayed as animated in the Answers forum but I don't think the Run feature can produce the animated image and display it on it's own, though I haven't tested it recently.
