function varargout = untitled(varargin)

% UNTITLED MATLAB code 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 "GUI allows only one

% instance to run (singleton)".
