PCA的步骤:
1 先将数据中心化;
2 求得的协方差矩阵;
3 求出协方差矩阵的特征值与特征向量;
4 将特征值与特征向量进行排序;
5 根据要降维的维数d’,求得要降维的投影方向;
6 求出降维后的数据;
(PCA steps: 1 of the first data center 2 covariance matrix obtained 3 obtained covariance matrix eigenvalues and eigenvectors 4 eigenvalues and eigenvectors will be sorted 5 according to the dimension of dimension reduction d ' , seek to reduce the dimension projection direction 6, the data obtained after the dimensionality reduction )

internet_down_load
分析一个文件夹及其子文件夹下所有的html文档,并查找文档中加载的png图片文件,通过urlwrite函数下载并保存png类型的图片文件到硬盘上。
此matlab代码用到了网络连接,下载,并且通过多线程技术,增加了下载的速度。
可以通过这个方法,下载网页中的内容,可以说想怎么下,就怎么下。(Analysis all the files of type html in a folder, find the documents that load png image file.Then download and save the png file to harddisk through urlwrite function .)

2-LMS-equalizer
说明: 假设每个延时单元延时10ms.被传输的基带信号x(t)是一个0,1交替变换的矩形二进制脉冲序列,脉宽为10ms,并假设x(t)通过一个稳定的散射信道后才到达均衡器,成为2径信号,这两路信号幅度相等 ,相隔15ms。用MATLAB实现一个2级LMS均衡器(equalizer)
