寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

偏微分方程的数值解法的MATLAB程序介绍了应用最为广泛的椭圆型、双曲型、抛物型偏微分方程的数值解法，而且还详细编程实现了每种方程的多种常见数值解法。 附件使用MATLAB编程来实现这些算法(introduces the most widely elliptic, hyperbolic, parabolic partial differential equations numerical solution, but also the details of each programming a variety of common numerical solution of equations. Attachments using the MATLAB program to implement these algorithms)

本程序为故障选相程序，可以区分接地与不接地故障。没有做故障发生判断，最好在故障时启动。(This program is the fault phase selection procedures, can differentiate between grounding and ground fault. Not make a fault judgment.)
