Using MATLAB for presentations

Now that MATLAB 5.0 has truecolor, I can not only generate images (with
very large color maps) but I can also display them.

I would like to take advantage of this and use MATLAB to present images
for my research. However, I would like to remove menus and frames and
present images on black or other colored backgrounds. I would also like
to be able to record responses while this is going on (key presses,
mouse button, etc).

Is there a way to do this in MATLAB or with a MEX file someone has
written? (My platform is the power Mac.)

You can do all of these things in MATLAB 5. To make a window
without a menubar, set the figure 'menubar' property to the value
'none'. You can get rid of all window frames by creating a figure
whose position is the screensize. Below is an example of how to
create a window with a black background that fills the entire screen
and shows no frames or menus (at least under Windows and unix):

f = figure('menubar', 'none',... % turn off menubar
           'color', 'black',... % make black background
           'position', get(0,'screensize'),... % fill the screen
           'windowbuttondownfcn', 'MousePressCallback',...
'keypressfcn', 'KeyPressCallback');

The strings: 'MousePressCallback' and 'KeyPressCallback' are the names
of m-file functions you create to process key and mouse presses.
For more information, consult the online help-desk and the MATLAB 5 Graphics
Users' Guide.

Hope this helps,
