Best Answer

  1. The RUN function accepts a char vector containing the name of the script to execute. You're not passing it a char vector containing a name.
  2. Your script file includes at least two problematic commands that I recommend you remove.
  • CLEAR, which will clear the variables in the workspace of the callback function in which it's executed, including the GUI's handles structure, which would break execution of that callback function. This would be a bigger problem but for the third command you execute.
  • CLOSE ALL, which will close all open figures, including your GUI.
So unless you indicated to the user that pushbutton3 will close the GUI, they may be confused by its behavior. I would eliminate those two commands as well as the CLC command (your code doesn't need to clear the Command Window, so why do it?)
