这是我自编的PQ分解法小程序，采用极坐标形式表示节点电压。(This is my small self of the PQ decomposition process is expressed by polar coordinates node voltage.)

matlab web 技术，通过这个技术，能让不会使用matlab的人使用matlab(matlab web technology, the adoption of this technology, can not use matlab to use matlab)

说明：  图论的算法，包括floyd和其他一些应用于求最短路径问题的matlab程序(Algorithms of graph theory, including the floyd and other used for the shortest path problem in matlab program)

在一个具有几个顶点的连通图G中，如果存在子图G 包含G中所有顶点和一部分边，且不形成回路，则称G 为图G的生成树，代价最小生成树则称为最小生成树(If there subgraph G ' contains all vertices in G, and part of the side, and does not form a loop, then G' in a few vertices connected graph G is the spanning tree of a graph G consideration of the minimum spanning tree is called minimum spanning tree)

本程序是用经验模态分解(EMD)算法检测VF信号的，该算法的灵敏度和特异性都达到了90 以上。(This procedure is used empirical mode decomposition (EMD) algorithm to detect VF signals, the sensitivity and specificity of the algorithm has reached more than 90 .)

变模式分解（Variational Mode Decomposition），实现非线性、非平稳信号处理，解决经验模式分解（emd）缺陷，包含代码和对应的文章(Variational Mode Decomposition,non-station, non-linear signal processing, decompose a signal into different modes,improved emd method. include code and its corresponding paper)

从MIDI文件中读取多基频，用于检测多基频的提取，是一个很好的方法，大家可以借鉴一下(MIDI multipitch )
