Do you still intend to get the saved figures as output? If not, I'd just define a logical flag that expresses whether plots should be created. Put all the plots inside conditional statements.

createplots = true;
% ...
if createplots
    plot(stuff,things);
    % ...
end

Is there something wrong with just doing that?

[Tyler Lawson]

So I need the .fig file and a .jpg file to save like they currently do. However when running a decent amount at once, I don't want each matlab figure to have to open and then close as it takes time. I tried doing the visibily off but then I cant open the matlab figure later once it is saved unless I open matlab and run a code to view it.

[Simon Chan]

Set the figure to invisble and use f as the handle in the following example if needed.

f = figure('Visible','off')

[Tyler Lawson]

I tried this... however, the file saves and then I cannot open the figure to make changes or zoom in or whatever later if I wanted.
