介绍和分析最大互相关匹配算法，并对其的性能进行分析(Introduction and analysis of the largest cross-correlation matching algorithm and its performance analysis)

本源码是一个用Matlab7.1实现的Kalman的源代码 ，他实现了基本的Kalman网络算法。(The source is a Matlab7.1 achieved using Kalman s source code, he realized the basic Kalman network algorithm.)

复数计算，使用类来做的，可以选择自己要计算的方式(Complex calculation, using the class to do, and can choose their own way to calculate the)

MATLAB教材学习资料 matlab的90个实例 matlab的90个中的1-5个(matlab studying ！)

this is the code of facial recognition system

说明：  将数组a[0]~a[size-1] 中重复的字母删除（仅仅保留第一次出现的字母，后续的重复字母均删除）(The array a [0] ~ a [size-1] Remove duplicate letters (just the first time to retain the letters, follow-up letters were removed duplication))

判断半正定矩阵与正定矩阵间的一种新的准则，gky方法是判定系统是否稳定的一种很有效的方法，里面有源代码和相应文档(Judge half positive definite matrix and the positive definite matrix, a new criterion between gky method is to determine whether the system stability of a kind of very effective method, there are source code and documentation accordingly)

PCA又为主成分分析，是一种特征提取方法， 它通过线性变换寻找一组最优的单位正交向量基，用他们的线性组合来重构原样本(PCA and the main component analysis, a feature extraction method, which by finding a set of optimal linear transformation unit orthogonal base vectors, with their linear combination to reconstruct the original sample)
