Full screen image display (without the frame)

[Jim River]

When an image is displayed, there is always a frame around it. Is it
possible to get rid of the frame? And how to display a full screen
image without the frame? (similar function in Powerpoint)

Thanks,
Jim

unfortunately, there isn't a function/mode that does quite what you
want.
a few things, however, will make your fig <grand>

% 1) apply the screen size to the fig size
p=get(0,'screensize');
set(gcf,'position',p);
% 2) get rid of the toolbar(s)
set(gcf,'windowstyle','modal');
% ... with some drawbacks!
