LISTING PROGRAM

1. Menu

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

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

%

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

%

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

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

%

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

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

% applied to the GUI before MENU_OpeningFunction gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to MENU_OpeningFcn via varargin.

%

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

% instance to run (singleton)". %
