Matlab code for calculation of spectrum density of G729 coder

说明：  面波数值模拟，交错网格法高阶有限差分数值模拟算法(Surface wave numerical simulation)

利用matlab软件平台生成音乐音符，7个音符，不同的乐器实现(create a music tone)

openExcel :用Matlab打开启动Excel服务器，并返回Excel活动页的句柄H jitt : 利用传入的周期向量，计算频率抖动 norma : 把计算得到的向量平均采样为30个点 interest ： 复利计算方法 myvad : 通常vad算法只能得到汉语普通话一声、二声和四声的语音，对于三声，中间因为有嘎裂，就是突然基频变得很低并且不规则，vad算法把一个音节往往切分为两个音节，myvad解决普通话三声的问题 (Open Excel sever by Matlab, and returen a handle of Excel active sheet)
