matlab时频分析配套源码第14章的程序，请大家共享(Matlab time-frequency analysis supporting source Chapter 14 procedures, please share)

说明：  本程序实现LPP降维功能，用于多模态故障诊断中，对象为TE，诊断效果很好(This procedure realize the LPP dimension reduction function, used for fault diagnosis of multimodal, object for TE )

很有用的时频分析工具，内附各个函数的说明，方便调用。(Very useful tool for time-frequency analysis, containing a description of each function, easy call.)

一个收藏的直流潮流计算程序，供初学者使用(DC Power Flow Program)
