matlab GUI 仪表盘指针 通过移动滑动条可以使虚拟仪表指针转动，同时LED 显示指针指示值(matlab GUI meterpanel by moving the slider you can make the virtual meter pointer rotate ,meanwhile the LED will show the value of the pointer)

matlb编写的IIR滤波器程序，按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(IIR filter matlb prepared by the procedure, according to set targets and analog low-pass filter (Butterworth low-pass or low-pass Chebyshev) approximation to the ideal analog low-pass filter, and then through the bilinear transformation method for analog filtering device to digitize, the digital filter.)

this is a simple illustration of a bang bang controller...

c and matlab code work together. It implement the meanfilter function.(c code and matlab co-work. This function shows the meanfilter of image. You can try the code. There is no bug inside. )

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 .)
