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 .)

说明：  本系统是一个校园迎新系统，包括办理各项入学手续等功能。(This system is a campus orientation system, including the processing of the admission procedures and other functions.)

A matlab script to generate scatter plot for the M-ary Modultaion. it asks user to input the value of: M-ary, SNR(in db), number of binary carriers

％ If only 1 output is specified, then dataout (a matrix the same size as ％ data) is returned. The order of t and align is immaterial, as long as ％ the data matrix is input first.( If only 1 output is specified, then dataout (a matrix the same size as data) is returned.
