    function varargout = mygui3(varargin)
% MYGUI3 M-file for mygui3.fig
%      MYGUI3, by itself, creates a new MYGUI3 or raises the existing
%      singleton*.
%
%      H = MYGUI3 returns the handle to a new MYGUI3 or the handle to
%      the existing singleton*.
%
%      MYGUI3('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in MYGUI3.M with the given input arguments.
%
%      MYGUI3('Property','Value',...) creates a new MYGUI3 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before mygui3_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to mygui3_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
