Is the MATLAB gui written in Java?  There is a known bug in the Java
windowing code which prevents it from working correctly with
non-reparenting window managers like xmonad.  Fortunately, there is a
workaround in the Java code which makes things work again, as long as
the current window manager it Compiz or Looking Glass 3D.  One of the
contrib modules (XMonadContrib.SetWMName) fiddles the X-property
settings so that xmonad pretends to be LG3d; the author claims that this
makes Java programs work correctly.
