function varargout = untitled1(varargin)

% UNTITLED1 MATLAB code for untitled1.fig

%????? UNTITLED1, by itself, creates a new UNTITLED1 or raises the existing

%????? singleton*.

%

%????? H = UNTITLED1 returns the handle to a new UNTITLED1 or the handle to

%????? the existing singleton*.

%

%????? UNTITLED1('CALLBACK',hObject,eventData,handles,...) calls the local

%????? function named CALLBACK in UNTITLED1.M with the given input arguments.

%

%????? UNTITLED1('Property','Value',...) creates a new UNTITLED1 or raises the

%????? existing singleton*.? Starting from the left, property value pairs are

%????? applied to the GUI before untitled1_OpeningFcn gets called.? An

%????? unrecognized property name or invalid value makes property application

%????? stop.? All inputs are passed to untitled1_OpeningFcn via varargin.

%

%????? *See GUI Options on GUIDE's Tools menu.? Choose "GUI allows only one

%????? instance to run (singleton)".
