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.)

matlab 批量读DBF文件，非常好用，需要下载一个dbfread函数文件(matlab batch read DBF files, very easy to use, need to download a dbfread function file)

Hamming 7,4 Viterbi Encoding and Decoding Algorithm step by step procedure explained

此程序是针对二元精馏塔建模，控制回流比以及进料流量来影响上层轻组分产品的浓度。分别用机理建模和最小二乘建模的方法，对精馏塔对象进行建模并比较两种模型之间的差别及分析原因。黄老师的系统辨识大作业。(This program is for two yuan distillation modeling, concentration control of reflux ratio, the feed flow rate to influence the upper light component products. Respectively by mechanism modeling method and the least square modeling, modeling of objects and the difference and reason analysis of distillation column comparison between two models. Large operating system identification of yellow teacher.)
