matlab编写的m函数文件，输入为两个点得经纬度坐标，输出为A点相对于B点得方位角。(matlab write a function of m file, enter the latitude and longitude coordinates for two points was the output of A point relative to point B have azimuth.)

非常经典的最优化程序，里面黄金分割、拟牛顿、对偶单纯形，故向大家推荐(Very classical optimization procedures, which Golden Section, Quasi-Newton, dual simplex, so to recommend)

物理下行信道的加扰，加扰子模块，需要自己设定参数，即可运行(Physical downlink scrambling, scrambling module, need to set parameters, you can run it )

说明：  3G网络WCDMA,基于matlab的仿真应用，以及CDMA通信系统的仿真(3G networks WCDMA, matlab-based simulation applications and simulation of CDMA communication systems)

8节点潮流计算程序，matlab配电网。电力系统的分析和计算中，需要不同网络结构和参数。在应 用这些参数之前，收集和整理工作会花费大量的时间和精力。(8-node flow calculation program, matlab distribution network. Power system analysis and calculation, require different network structures and parameters. Before applying these parameters, the collection and collation will spend a lot of time and effort.)

这是Chambolle的投影算法（projection algorithm）的matlab 代码。proj.m为主程序，另外两个为调用程序。(This is the Chambolle' s projection algorithm of the matlab code. proj.m the main program, the other two for the caller.)

This code is NUMBER1: MATLAB code for paper: calculation of electron energies in a quantum well using the transfer matrix method. we solve the time independent schrodinger equation in 1D AlGaAs/GaAs/AlGaAs quantum well using the transfer matrix method. We define a wave function for each point of well and barriers and convert it to a 2in2 matrix. Multiplying of matrixes with boundary conditions results in discrete energies and their wave functions. We compare our results with other simulations and calculate discrete energies for different wells.

卡尔曼滤波比较简单的代码和相关文章！对于初学者还是比较有用的(Kalman filtering relatively simple code and related articles! It is quite useful for beginners)

Blind Source Seperation (BSS) now is a important technology. Independent Component Analysis (ICA) is the main technique of BSS. Suppose we mix many non-Gausse signal sources,ICA can seperate the mixed signal to orignal signals without any information. This Matlab Code simulate the using ICA for Multi User Detection (MUD) in CDMA system. We demo the CDMA system with 30 Users, and use ICA seperate the signal of each user at Base Transmit Station (BTS) with the only 30 Users signal.
