matlab GUIs

I have a main GUI from which I can open several sub GUIs. I need to write a code such that when I open the sub GUIs, first sub GUI should be closed when I open the second sub GUI but the main GUI should remain open. Can anyone help me out with the code?

Hmm, maybe 'findobj' could work. I tried some code that seemed to work:

% Find all figures
list_of_figs = findobj('type','figure');

% The latest opened figure, should be in the end of the list.
sub_fig      = list_of_figs(end);

% Close the figure
close(sub_fig);

Or you could open you sub GUI's using the same name for all of them (since you won't have more than one open at a time anyway), and then just use close(sub_fig_name).
