				function varargout = untitled3(varargin)
				% UNTITLED3 M-file for untitled3.fig
				%      UNTITLED3, by itself, creates a new UNTITLED3 or raises the existing
				%      singleton*.
				%
				%      H = UNTITLED3 returns the handle to a new UNTITLED3 or the handle to
				%      the existing singleton*.
				%
				%      UNTITLED3('CALLBACK',hObject,eventData,handles,...) calls the local
				%      function named CALLBACK in UNTITLED3.M with the given input arguments.
				%
				%      UNTITLED3('Property','Value',...) creates a new UNTITLED3 or raises the
				%      existing singleton*.  Starting from the left, property value pairs are
				%      applied to the GUI before untitled3_OpeningFunction gets called.  An
				%      unrecognized property name or invalid value makes property application
				%      stop.  All inputs are passed to untitled3_OpeningFcn via varargin.

				%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
				%      instance to run (singleton)".
