function varargout = simple_gui(varargin)
% SIMPLE_GUI MATLAB code 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.  All inputs are passed to simple_gui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
