title: Global variables in MATLAB GUI?
body: <p>I'm working with MATLAB GUI.</p>
  
  <p>When I'm trying to access the variable which was defined with the push button, it is not defined in the pop up menu. The variables; it should be set 'global', so it is defined in the whole program. And I can use it in any callback.</p>
  
  <p>Do you guys have any idea of how to make the variables 'global'?</p>
