knn-K近邻法实现两分类的函数代码，输入为两类的样本特征，和待测试的样本向量，输出为分类结果。(knn-K nearest neighbor method to achieve the two categories of function code, enter the characteristics of two types of samples, and samples to be tested vector, the output for the classification.)

说明：  比较全的matlab的算法！经典算法都有哦！(All of the matlab algorithms compare! Classical algorithms are Oh!)

改进的Cholesky分解的过程演示，本人原创，测试无误，内含详细注释。 (Cholesky decomposition process improvement presentation, my original test and correct, containing detailed notes.)

Numerical analysis: Newton method used to solve the nonlinear problems.

说明：  1、对原文《线性时滞系统的记忆与无记忆复合H∞状态反馈控制》仿真例子作了修正。原例子根据定理1没有解。 2、对该控制方法利用matlab lmi工具箱做了仿真验证。(matlab lmi toolbox)
