一、简介
基于matlab GUI 动感音乐播放：
1 *选择本地音乐；
2 播放音乐的同时还有行走人的动画；
3 人的速度和姿态都可调整；
4 还可输入文本；
二、源代码
function varargout = hdm_player(varargin)
% HDM_PLAYER MATLAB code for hdm_player.fig
% HDM_PLAYER, by itself, creates a new HDM_PLAYER or raises the existing
% singleton*.
%
% H = HDM_PLAYER returns the handle to a new HDM_PLAYER or the handle to
% the existing singleton*.
%
% HDM_PLAYER('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in HDM_PLAYER.M with the given input arguments.
%
% HDM_PLAYER('Property','Value',...) creates a new HDM_PLAYER or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before hdm_player_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to hdm_player_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
