直接型IIR滤波器实现源代码，希望与大家共同分享！(Direct IIR filter source code, I hope to share with you!)

一个简单的风场模型，适用一般的仿真应用，程序运行准确(A simple wind field model for simulation of general application, the program runs exactly)

人脸识别，使用深度学习中的DBN算法进行人脸识别算法，数据集是ORL人脸数据集。(FACE Recognition, using the depth learning DBN algorithm recognition algorithm, the data set is a ORL face dataset.)

matlab实用程序百例2 很实用的 对初学者大有裨益(Matlab program the practical example 2 is very useful for beginners greatly )

该程序可以实现信号的分形计算，从而求解出所求信号的分形函数，在信号非线性研究中有很重要的作用。(The program can calculate the fractal signal, thus solving the request signals a fractal function, the study of nonlinear signal has a very important role.)

说明：  本程序为粒子群算法的源代码可应用于微电网的多目标经济优化调度(This program is the source code of particle swarm optimization algorithm and can be applied to multi-objective economic optimal dispatch of microgrid)

当要隐藏信息时,在MATLAB的命令窗内输入命令: hide = myhide(carry,signal,x,y)； carry 用你的原始载体文件名代替，signal 用你所要隐藏的文件名代替 carry 和 signal 都必须是 *.* 的形式（注意不能省略单引号） x,y 是选取隐藏信息的位置坐标，在（x,y）和（y,x）处 生成的伪装载体文件名为hide.bmp 注意myhide.m文件，载体文件，隐藏文件都要在当前目录(current Directory)下 当要提取信息时，在MATLAB命令窗内输入命令： behidden = myinhide(carry,x,y)； carry 用你的伪装载体文件名代替,格式为 *.* （注意不要丢掉单引号） x,y 是选取隐藏信息的位置坐标，在（x,y）和（y,x）处，这必须和嵌入时所选位置一致。 提取出的信息文件名为behidden.bmp 同样，要注意behidden.m和伪装载体文件都要在当前目录(current Directory)下(when to hide information, in order MATLAB within a window orders : hide = myhide (carry, signal, x, y); Carry with you the original document name instead vector, signal used to hide your name in the paper and instead carry signal must be in the form of*.* ( not to single quotes omitted) x, y is to select the location of hidden information coordinates (x, y) and (y, x) The formation of camouflage vector document, entitled hide.bmp attention myhide.m documents, vector documents hidden all the documents in the current directory (current Directory) to retrieve information when, in order window MATLAB import order : behidden = myinhide (carry, x, y); carry using your camouflage vector file name instead, the format for*.* (take care not to lose a single quote) x, y election Hiding information )

刘金琨教授写《滑模变结构控制matlab仿真》随书程序源码(Professor Liu Jinkun write " Sliding Mode Control matlab simulation" program source code with the book)

对基于软件无线电的gps系统进行了完整论述，介绍gps系统软件接收机的最新研究成果的时机已经成熟，同时介绍即将投入使用的欧洲伽利略导航系统。利用matlab(版本7．x)作为编程语言，其提供了非常强大的绘图功能，可以直观清楚地显示数据的结果。(Gps software radio-based system for a complete discussion of system software gps receiver introduces the latest research results of the time is ripe, will soon also introduced into the European Galileo navigation system to use. Using matlab (version 7.x) as a programming language, it provides a very powerful graphics capabilities, you can visually display the data the results clearly.)

说明：  介绍了常用的MATLAB 图像处理命令，并用实例说明用法(Describes commonly used MATLAB image processing commands, and use examples of usage)
