二、源代码
function varargout = music_show1(varargin)
% MUSIC_SHOW1 MATLAB code for music_show1.fig
% MUSIC_SHOW1, by itself, creates a new MUSIC_SHOW1 or raises the existing
% singleton*.
%
% H = MUSIC_SHOW1 returns the handle to a new MUSIC_SHOW1 or the handle to
% the existing singleton*.
%
% MUSIC_SHOW1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MUSIC_SHOW1.M with the given input arguments.
%
% MUSIC_SHOW1('Property','Value',...) creates a new MUSIC_SHOW1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before music_show1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to music_show1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
