compressed--sensing-

这是关于利用小波变换进行二层压缩的小程序，利用小波工具箱，进行图像编码，分层，解压缩，最后还原。(This is a program about wavelet)

该函数实现的功能是去掉A中与b相同的元素(the function is used to cut the sane member(a)which appeared in a arrray(A) from the array(A) )

一些常用的小程序，具有较高的可重用性。另外都可以运行。(Small number of commonly used procedures, have a high reusability. Also can be run.)

PID控制器的模型仿真，结果三环的仿真正确(PID controller model simulation, the results of three-ring of the simulation correctly)

金融工程嗯, 从matlab论坛上下载的，我觉得很有用，所以传上来分享(Financial Engineering derivatives from famous University and is really useful in derivatives. I love it very much and I think is really helpful to your guys)
