三、部分源代码

function varargout = beautiful2(varargin)
% BEAUTIFUL2 M-file for beautiful2.fig
% BEAUTIFUL2, by itself, creates a new BEAUTIFUL2 or raises the existing
% singleton*.imaqhwinfo
%
% H = BEAUTIFUL2 returns the handle to a new BEAUTIFUL2 or the handle to
% the existing singleton*.
%
% BEAUTIFUL2('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in BEAUTIFUL2.M with the given input arguments.
%
% BEAUTIFUL2('Property','Value',...) creates a new BEAUTIFUL2 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to beautiful2_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
