"Is there some internal limit on figure windows that can be set"
Not that I'm aware of. Matlab will crash when it reaches memory capacity.
Here are some suggestions to manage the debugging figures situation.
Set a debug flag that conditionally creates the figures
Instead of manually commenting/de-commenting the debugging sections of your code, set an internal flag at the top of your file that indicates when the debugging sections should be accessed. Then put all of the debugging sections into conditional statements. Here's a template.
% Top of code
debugMode = true;
% Confirm that user wants to use debug mode
if debugMode
% This is optional, it's to let the user know when you're in debug mode.
resp = questdlg('Do you want to continue with debug mode?',mfilename, 'Yes','No','Yes')
if isempty(resp) || strcmpi(resp,'No')
error('Debug mode cancelled.')
end
end
% within your code
if debugMode
figure(1)
plot( . . .)
end
Set the figure number
Instead of creating a next figure via figure(), set the figure number using figure(1), figure(2), etc. This way if you have 10 debugging figures and the code is repeated, those 10 figures will be overwritten instead of an additional 10 figures being created.
Use clf() instead of creating new figures
The clf() command either clears the current figure or creates a new one if a figure doesn't already exist. By using clf() instead of figure(), you're always reusing the same figure instead of creating multiple figures. However, if your code creates multiple debugging figures, each one will be overwritten.
