矢量匹配算法，关于曲线理和的问题，能克服有理匹配的相关缺陷(vectfiting )

这是一个半导体激光器弛豫振荡现象的仿真程序，计算参数和速率方程模型都取自经典教材Semiconductor Lasers(Agrawal 著)，可以作为学习和进一步研究半导体激光器各种动态特性的基础材料。(This is a simulation program by Matlab for calculating the oscilating in semiconductor lasers, in which the rate equation model and the parameters used are all from the classic technical monograph by Agrawal. This could be a basic material for further investigating and studying different dynamic activities of semiconductor lasers. )

K-mean matlab code example

求两个时间序列的相关系数，KL散度。可以比较时间序列之间的相关性(KL divergence && correlation coefficent)

由于Kmeans聚类分析是一个局部的搜索过程，因此加入遗传算法进行全局搜索选择最优的初始中心点使得Kmeans算法产生较大的改进(Since Kmeans Cluster analysis is a local search process, so join a global search for the genetic algorithm to the optimal initial centers such Kmeans algorithm produces greater improvement)

如关键词，本人搭建的，在matlab2016b上测试。(For example, keywords, built by myself, are tested on MATLAB 2016b.)

说明：  前半部分仿真可能是对的 ，但是后面求频偏估计均方误差与定时估计均方误差的图像时，就不对了。希望告诉们能给我解答一下(code about OFDM)

对非同步采样数据进行三次样条插值同步化处理，进而可进行谐波分析。(The asynchronous sample data can be synchronized by using the interpolation of cubic function)
