说明：  关于大型机的内容，是cobol语言，大家可以仔细研习(Content on the mainframe is the cobol language, we can carefully study)

说明：  kmeans和dbscan的聚类算法的matlab实现(Matlab implementation of clustering algorithm based on kmeans and DBSCAN)

matlab的随机数生成算法， 产生伪随机数(matlab random number generation algorithm to produce pseudo-random number)

Arithmetic 数值计算，包含了可以用matlab就是的一般常用数值计算(Numerical Calculation of Arithmetic, contains matlab can be used is the commonly used numerical)

MEX- Matalb executable helps is running c programs in matlab.

In this Simulation File, we design contol plant of HyperChaotic Sysytem, Chen System is the important Hyper Chaotic. We control this system with Sliding Mode Control First Order And Result show this method is good for this nonlinear System.

机器学习中的垃圾邮件分类程序，用matlab做的。从以下链接下载垃圾邮件数据（spam data）：(数据已下载，放在spambase.zip) http://www-stat.stanford.edu/~tibs/ElemStatLearn/index.html 该数据包含57个邮件信息相关的变量，每条邮件可以被分类为垃圾邮件（Y=1）和非垃圾邮件（Y=0）。输出Y的值在文件中每一列的末尾。练习的目标是要预测电子邮件是否为垃圾邮件。 (Machine Learning spam classification procedures, using matlab to do. Data (spam data) from the following link to download the junk mail: (data has been downloaded, put spambase.zip) http://www-stat.stanford.edu/ ~ tibs/ElemStatLearn/index.html The data includes 57 e-mail messages related variables, each message can be classified as spam (Y = 1) and non-spam (Y = 0). Y value of the output end of each column in the file. The goal is to predict exercise email is spam.)

在进行车牌识别的预处理过程中,如何有效地提高车牌图像质量是一个关键,这一步处理的好坏将直接影响到后面车牌识别的效果。 本文重点研究直方图修改技术增强图像方法在车牌识别预处理中的应用,给出了直方图修改技术的原理,以及直方图均衡化、规定化和对比度调整的原理,最后用MATLAB来实现车牌图像增强的效果。(License Plate Recognition in the pre-treatment process, how to effectively improve the image quality license plate is a key to dealing with the merits or demerits of this step will directly affect the effectiveness of the back license plate recognition. This article focuses on the image histogram modification method to enhance license plate recognition in the pre-processing of applications, given the principle of histogram modification techniques, as well as histogram equalization, contrast adjustment provisions and the principles of using MATLAB to achieve the final vehicle the effect of brand image enhancement.)

基带系统的蒙特卡罗仿真，眼图程序，多径信道均衡，信道传输函数(baseband system Monte Carlo simulation, eye procedures, multi-path channel equalization, channel transfer function)

说明：  gen_H:利用随机pi矩阵排列而成的LDPC稀疏校验矩阵产生； girthlenth：计算产生的矩阵H的围长(gen_H : pi using random matrix arranged at the LDPC have sparse matrix calibration; girthlenth : calculation of the matrix H Girth)
