When arranging figures using gcf, Java Heap Space Error

I am trying to nicely arrange some figures on my screen in an array. I used the following, relatively poor code to try to assign each figure to a spot on the screen, but whenever I run it I get a Java Heap Space Overload error that stalls MatLab and forces me to quit:

     screen = get(0, 'screensize');
     %declare how many graphs wanted on screen
     graphsWide = 4;
     graphsTall = 3;

     graphPos = screen * diag([0 (screen(4)*(graphsTall-1))/graphsTall...
     screen(3)/graphsWide screen(4)/graphsTall]);

     shiftRight = [graphPos(3), 0, 0, 0];
     shiftDown = [0, graphPos(4), 0, 0];

     graphIndex = @(i, j) (graphPos+((i-1)*shiftRight)+((j-1)*shiftDown));

     for i = 1:12
         figure(i);
         set(gcf, 'position', graphIndex(i mod 4, floor(i/4));
     end

Any ideas as to where I am going horribly wrong?

I'm not sure exactly where you went wrong, but a much easier solution to laying out figure windows in a nice grid is to dock them and then use the tile option in the Window menu. You can un-dock the figures panel from the editor but still have all the figures docked in the panel.

f = figure('WindowStyle','docked')  % Create a new docked figure
set(gcf,'WindowStyle','docked')     % Dock an existing figure

Just what I wanted and it's built in. Thanks so much for showing me that. As for the code… I wish I knew what was wrong but I'll live with a workable solution.

Is the problem reproducible? Did you restart Matlab and the computer already? Did you install a new Java version and work e.g. on a Mac? When did this problem start to happen? Did Matlab work correctly before? Did you try to re-install Matlab?
