Figure positioning trouble on Ubuntu

I'm running Matlab R2013b on Ubuntu 12.04, and I've noticed that it's not possible to change on-screen figure sizes from the command line. That is, something like
mypos=get(gcf,'position');
set(gcf,'position',[mypos(1) mypos(2) mypos(3)+100 mypos(4)+100]);
which I'd expect to grow the figure by 100 pixels in each direction, has no effect. This works fine on every other Matlab installation I've used. Can anybody help? Has 2014a fixed this problem?

Maybe you mean "undocking" instead of "unlocking"? The figure isn't docked. But after more experimenting, I found that if I
set(gcf,'resize','off');
(which disables resizing the window with the mouse), then I am able to resize from the keyboard, using commands like the one above. It's a good-enough workaround, if a strange one.

Yes, undocking Matlab. Sorry about that.

You might have the units as "characters" or "normalized". If you want "pixels", try it this way:
set(gcf,'Units', 'Pixels', 'Position', [mypos(1), mypos(2,) mypos(3)+100, mypos(4)+100]);
Let us know if that works.
