function varargout = untitled4(varargin)
% UNTITLED4 M-file for untitled4.fig
% UNTITLED4, by itself, creates a new UNTITLED4 or raises the existing
% singleton*.
%
% H = UNTITLED4 returns the handle to a new UNTITLED4 or the handle to
% the existing singleton*.
%
% UNTITLED4('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED4.M with the given input arguments.
%
% UNTITLED4('Property','Value',...) creates a new UNTITLED4 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled4_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled4_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
