Try this:

% Load the image variable from the MAT file into a structure s.
s = load(yourFileName);
% Extract the image from the structure
rgbImage = s.ImageName; % Or whatever the image variable is named.
% Write to disk in a jpg format, which you should never use for image analysis.
imwrite(rgbImage, 'my image.jpg');

Why should I never use the image for image analysis?

Because jpeg is a lossy file format (technically it is possible to have lossless settings for jpeg, but nobody uses it). That means you will lose data when storing as jpeg, meaning your analyses will be less reliable.
