Matlab小波去噪程序，原创程序，很完整。(Matlab wavelet denoising procedure, original proceedings, it is complete.)

说明：  《MATLAB在数字信号处理中的应用》 介绍matlab6.1在数字信号处理领域的基本原理和应用(err)

在matlab下运行，产生标准均匀分布，正态分布和指数分布的随机数发生器程序。(In matlab running, generate standard uniform, normal and exponential distribution random number generator program.)

异构网络垂直切换算法的源代码，该代码的功能是移动台在三个网络之间的状态。(Heterogeneous network vertical handoff algorithm source code, which is a mobile station state functions between the three networks.)

这是天津大学胡清华老师在粗糙集邻域领域做的最经典的源码，同学们可以在此基础上学习和修改，入口程序已经写好，需要其他方法可以自己添加，MAIN.m是入口程序，参数的意思在子函数里讲的很明白，调用了featureselect_FW_fast.m用来属性约简，几个clsf_dpd文件是使用不同的距离公式来计算属性重要度，选择得到属性结果，使用crossvalidate.m十折交叉算法来计算计算算法精度，该段代码调用了几个分类器，C4_5.m是决策树，KNN.m是最近邻分类器，NEC.m是类似于KNN的胡修改的程序，osu_svm3.00文件夹是使用svm分类器调用的文件，使用该分类器时，代码中间的路径需要修改。另外附上一堆常用的数据集。(This is Hu Qinghua teacher at Tianjin University neighborhood rough set field do the most classic source code, students can learn and modify On this basis, the entry procedures have been written, you need other ways to add your own, MAIN.m entry program is meaning parameters Functions talked in very clear call for the featureselect_FW_fast.m attribute reduction, several clsf_dpd file is to use a different formula to calculate the distance attribute importance, choose properties to get the results, use crossvalidate.m ten fold cross algorithm to calculate the accuracy of the calculation algorithm, the segment code calls several classifiers, C4_5.m is a decision tree, KNN.m is the nearest neighbor classifier, NEC.m is similar to KNN Hu modified program, osu_svm3. 00 folders using svm classifier called file, using the classification code in the middle of the path need to be modified. Also attach a bunch of common data sets.)

针对数字图片的各种攻击方法，使用Matlab编写。(Digital images for a variety of attack methods, the use of Matlab to write.)

This script creates a diagram showing OFDM signals in the time domain. This shows that each of the carriers in the signal have an integer number of cycles making them orthogonal.

基本和声搜索算法优化经典函数问题，运行效果还可以。和声搜索算法是新近的智能优化算法( Harmony search algorithm for classic function optimization problem.)
