Demo2.m file is below one:
function varargout = Demo2(varargin)
% DEMO2 MATLAB code for Demo2.fig
%      DEMO2, by itself, creates a new DEMO2 or raises the existing
%      singleton*.
%
%      H = DEMO2 returns the handle to a new DEMO2 or the handle to
%      the existing singleton*.
%
%      DEMO2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in DEMO2.M with the given input arguments.
%
%      DEMO2('Property','Value',...) creates a new DEMO2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Demo2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Demo2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
