本人在攻读博士期间开发的用于求解城市道路交叉口绿波控制参数的遗传算法(The code was developed during the period of my study for Ph.D. degree, it can be used to solve the urban intersections green wave control problem, the method used in the coed is Genetic Algrothims)

说明：  遗传算法 C语言源码Denis Cormier (North Carolina State University)开发的，Sita S.Raghavan (University of North Carolina at Charlotte)修正，很实用(GA C language source code Denis Cormier (North Carolina State University) developed, Sita S. Raghavan (University of North Carolina at Charlotte) amendments, it is practical)

MATLAB入门,有利于快速熟悉MATLAB(MATLAB portal is conducive to rapid familiar with MATLAB)

在matlab开发环境下用k均值算法实现数据的分类，以及得到数据的聚类中心( realizingthe data classification With k-means algorithm)

K最邻近密度估计技术是一种分类方法，不是聚类方法。 不是最优方法，实践中比较流行。 通俗但不一定易懂的规则是： 1.计算待分类数据和不同类中每一个数据的距离（欧氏或马氏）。 2.选出最小的前K数据个距离，这里用到选择排序法。 3.对比这前K个距离，找出K个数据中包含最多的是那个类的数据，即为待分类数据所在的类。(K nearest neighbor density estimation is a classification method, not a clustering method. It is not the best method, but it is popular in practice. Popular but not necessarily understandable rule is: 1. calculate the distance between the data to be classified and the data in each other (Euclidean or Markov). 2. select the minimum distance from the previous K data, where the choice sorting method is used. 3. compare the previous K distances to find out which K data contains the most data of that class, that is, the class to which the data to be classified is located.)

说明：  微分进化算法可以求解大规模非线性的数学模型(Differential evolution algorithm)

this code can be use in prediction filter of seismic data.

二维，ＦＤＴＤ，ｐｍｌ，ｍａｔｌａｂ语言。(Two-dimensional, FDTD, pml, matlab language.)

说明：  如何在图像中加入一个冲击信号，求冲击信号的自相关 并求与高斯信号的互相关性(how to insert noise,and how to konw the correlation with gaosi noise)

matlab绘制三维Hilbert谱程序，保证可用。上传文件采用的是.txt形式，实际使用时只需要将后缀改为.m即可在matlab中运行。(matlab draw three-dimensional Hilbert spectrum procedures to ensure that available. Upload file uses a .txt form, the actual use of the suffix to .m only need to be run in matlab.)
