function varargout = simple_gui(varargin)% SIMPLE_GUI M-file for simple_gui.fig%      SIMPLE_GUI, by itself, creates a new SIMPLE_GUI or raises the existing%      singleton*.%%      H = SIMPLE_GUI returns the handle to a new SIMPLE_GUI or the handle to%      the existing singleton*.%%      SIMPLE_GUI('CALLBACK',hObject,eventData,handles,...) calls the local%      function named CALLBACK in SIMPLE_GUI.M with the given input arguments.%%      SIMPLE_GUI('Property','Value',...) creates a new SIMPLE_GUI or raises the%      existing singleton*.  Starting from the left, property value pairs are%      applied to the GUI before simple_gui_OpeningFcn gets called.  An%      unrecognized property name or invalid value makes property application%      stop.
