基于matlab GUI界面的播放器，用matlab环境控制播放、暂停、停止和回放源码程序

function varargout = testplay(varargin)

% TESTPLAY M-file for testplay.fig

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

% singleton*.

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

% the existing singleton*.

% TESTPLAY('CALLBACK',h ,eventData,handles,...) calls the local

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

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

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

% applied to the GUI before testplay_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

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

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

% instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help testplay
