function varargout = untitled(varargin) % UNTITLED M-file for untitled.fig

% UNTITLED, by itself, creates a new UNTITLED or raises the existing % singleton*. %

% H = UNTITLED returns the handle to a new UNTITLED or the handle to % the existing singleton*. %

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

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

% UNTITLED('Property','Value',...) creates a new UNTITLED or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before untitled_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to untitled_OpeningFcn via varargin. %

% *See GUI Options on GUIDE's Tools menu. Choose \% instance to run (singleton)\%
