指纹图像特征提取，采用matlab编程实现(Fingerprint image feature extraction, using matlab programming)

一个基于matlab的fsk仿真，加入了高斯白噪声(Fsk the matlab-based simulation, by adding a Gaussian white noise)

This function helps you to find moments from an Image

针对多径信道的信道均衡，演示了几种经典的算法。可以直接运行。画图时是动态的，做得很精细。(Multipath channel for the channel equalization, demonstrate several classic algorithms. Can be directly run. Paint is dynamic, so very fine.)

S－函数是System function 系统函数的简称，是指采用非图形化（即计算机语言，而非Simulink 系统模块）的方式描述的功能模块。在MATLAB 中，用户除了可以使用MATLAB 代码编写S－函数以外，还 可以使用C、C＋＋、FORTRAN 或Ada 语言编写S－函数，只不过用这些语言编写程序时需要用编译器生成 动态连接库（DLL）文件，然后在Simulink 中直接调用(S-function System Function system function, refers to the use of non-graphical (ie computer language, rather than the Simulink system module) way described functional modules. In MATLAB, the user can use MATLAB code to write the S-function outside can use C, C++, FORTRAN or Ada language preparation of the S-function, only in these languages ​ ​ to write programs need to use the compiler to generate dynamic link library (DLL ) file, and then called directly in Simulink)

matlabGUI简单的小程序，求解结构的自由振动频率。结合专业，顺便熟悉编程(matlabGUI simple little program to solve the free vibration frequency of the structure. Combined with professional, by the way familiar with the programming)

fisher线性鉴别分析 用matlab实现的源代码 对于ORL库德识别率达到96 以上(fisher Linesr discriminant analysis)

各种滤波器的设计，包括高斯低通滤波器。hilberrt带通滤波器，插值滤波器等等。(Various filter design, including Gaussian low-pass filter. hilberrt band-pass filter, the interpolation filter and so on.)

说明：  PSO的基本程序和3种经典的改进程序，包括GPSO，ARPSO和HPSO，文件包中没有附这三种改进PSO的源论文，请自行下载(PSO)
