这是数模中有关层次分析的源码，相信有需要的人!(This is the model on several levels of analysis of the source code, I believe those who are in need!)

This problem is main to solve a PDE. And we have validate hte program with the analysis results.

Lattice Boltzmann LBE模型在二维多孔介质流体渗流中的应用，基于geometry: D2Q9, model: BGK(Simple, yet simplistic, Lattice Boltzmann (LB) MATLAB implementation. D2H9, BGK, omega = 1, laminar flow in a 2D channel used as benchmark. Requires Image Processing Toolbox. )

orthogonal frequency division multiplexing using wireless networks

matlab code for cohernt communication systems in analog communications.

these are to set of files. first one is used for baro and inertial integration and the erro of inertial. the second one is used for sim of reentry by use of not only its dynamics but also with EKF observants to control reentry

说明：  实现了rip ospf bgp等路由协议的开源代码。(achieved a rip bgp OSPF routing protocol, such as open-source code.)

基本粒子群优化算法Matlab源程序 网上找到的别人做的很简单的程序，写的很精练很工整，据说优化效果不是很理想，由于没有时间去做很多测试，所以就先摆在这里，但愿以后能用得上。 下面是主函数的源程序，优化函数则以m文件的形式放在fitness.m里面，对不同的优化函数只要修改fitness.m就可以了通用性很强。 (Particle Swarm Optimization Algorithm Matlab source code online to find others to do the procedure is very simple, very concise writing is very neat, is said to optimize the effect is not very satisfactory, because there is no time to do a lot of testing, so I have to put in here, I hope that can use later. The following is the main function of the source, optimizing the function form of the document on Zeyi m fitness.m inside, as long as the different optimization functions can modify the fitness.m highly generic.)

均衡技术的matlab仿真。包括时域均衡和频域均衡后的信噪比对比(Equalization matlab simulation. Including time domain equalization and frequency domain equalization SNR comparison)

此程序相关卡尔曼滤波，用matlab描述了卡尔曼滤波的过程。(ocedure-related Kalman filtering, Kalman filtering with matlab describes the process.)
