title: How to run pushbutton callback outside of GUI in Matlab?
body: <p>I have GUI-A with <code>pushbuton_callback</code> that calculates the user input and display in GUI-A. Now, how can I run GUI-B that execute GUI-A pushbutton ? Or is there any way to tell the computer to click the GUI-A pushbutton in GUI-B?</p>
  
  <p>I have tried a command like:    </p>
  
  <pre><code>GUI-A('pushbutton_Callback',handles.pushbutton,[], handles).
  </code></pre>
  
  <p>But it pops up error that "handles are not defined."</p>
