基于crazy climber算法的数字调制信号脊特征提取(陈利民）(Crazy climber algorithm based on digital modulation signal feature extraction ridge)

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)
