title: how to position Matlab GUI window at top of screen?
body: <p>I used Matlab GUIDE to create a GUI.
  It is displayed mid-screen.</p>
  
  <p>How can I position it at the top of the screen; so that the top edge of the  GUI window is at top of screen.</p>
  
  <p>It will be used on different Windows 7 computers with different screen resolutions.</p>
  
  <p>I tried to set <code>hObject.Position(2)</code> but it doesn't do what I want.</p>
