【游戏】音乐时钟Matlab设计

1 简介

本文结合"数字信号处理"课程和"Matlab程序设计"课程的相关知识,给出了基于Matlab的音乐播放器的总体设计方案,介绍了播放器主要模块的功能,设计与实现方法.我们将该设计作为电子信息类专业数字信号处理课程设计项目,有助于激发学生的学习兴趣,提高其综合设计和应用创新能力.

2 部分代码

function varargout = untitled(varargin)

% UNTITLED M-file for untitled.fig

%      UNTITLED, by itself, creates a new UNTITLED or raises the existing

%      singleton*.

%

%      H = UNTITLED returns the handle to a new UNTITLED or the handle to

%      the existing singleton*.

%

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

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

%

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

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

%      applied to the GUI before untitled_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

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

%

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

%      instance to run (singleton)".
