  1. function varargout = GUI(varargin)
  2. % GUI MATLAB code for GUI.fig
  3. %      GUI, by itself, creates a new GUI or raises the existing
  4. %      singleton*.
  5. %
  6. %      H = GUI returns the handle to a new GUI or the handle to
  7. %      the existing singleton*.
  8. %
  9. %      GUI('CALLBACK',hObject,eventData,handles,...) calls the local
  10. %      function named CALLBACK in GUI.M with the given input arguments.
  11. %
  12. %      GUI('Property','Value',...) creates a new GUI or raises the
  13. %      existing singleton*.  Starting from the left, property value pairs are
  14. %      applied to the GUI before GUI_OpeningFcn gets called.  An
  15. %      unrecognized property name or invalid value makes property application
  16. %      stop.  All inputs are passed to GUI_OpeningFcn via varargin.
  17. %
  18. %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
  19. %      instance to run (singleton)".
