MATLAB: How to move the position of the GUI on the screen from the default

guiguidemoveguiposition change

I have a GUIDE gui made with MATLAB R2011a. Non of the following techniques has worked to move the gui on the screen:
1)use of
 movegui('center')
in the main Figure's CreateFcn or the gui's Opening function
2) use of this code in Opening function:
    %pixels
set( handles.figure_main, ...
    'Units', 'pixels' );
%get your display size
screenSize = get(0, 'ScreenSize');
%calculate the center of the display
position = get( handles.figure_main, ...
    'Position' );
position(1) = (screenSize(3)-position(3))/2;
position(2) = (screenSize(4)-position(4))/2;
%center the window
set( handles.figure_main, ...
    'Position', position );
3)or even simple commands of:
 set(handles.figure_main,'Units', 'pixels');
 set(handles.figure_main,'Position', [900 39 912 600]);
Any help is appreciated

the issue was resolved by restarting MATLAB!! There might have been a bug, but my guess is that had something to do with switching back and fort btw external and default monitor of my machine. I reset the position data in the position property of the main Figure of the gui and it worked after trying the same thing over and over!!
thanks for all your suggestions
