A related note: To get a figure to have a name you want, instead of like "Figure 1", "Figure 2", etc., you can turn the 'NumberTitle' property 'Off' and set the 'name' property of the figure to a literal string or a string variable:
% Give a name to the title bar/figure.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off')
