To calculate the Bit Error Rate (BER)of AWGN channel for a given range of SNR in MATLAB

随机森林，matlab程序编写，用于分类和回归(Random Forests, matlab programming for classification and regression)

matlab编写 wkb计算电磁波通过等离子体衰减(a matlab program to compute the attenuation of electromagnetic wave)

环境DEA 算法 ,加入环境因素考虑能源效率(Environmental DEA algorithms incorporate environmental factors into account for energy efficiency)

将断层剖面划分为一组网格，并以固定的事件数或固定的扫描半径，计算每个网格点处的b值。然后用色彩表示断层面上b值的分布情况，从而反应断层的应力积累情况，便于地震学家分析该断层是否存在发震的可能(This subroutine creates a grid with spacing dx,dy (in degreees). The size will be selected interactively or grids the entire cross section. The b-value in each volume is computed around a grid point containing ni earthquakes or in between a certain radius. The standard deviation is calcualted either with the max. likelihood or by bootstrapping, when that box is checked. If not, both options can be assigned by the additional run assignment. Standard deviation of b-value in non-bootstrapping case is calculated from Aki-formula!)

基于matlab的字母识别，基于模板匹配，因为采用区域生长法，速度可能有些慢！(Base on matlab!)

MATLAB仿真rake接收机，分三种方式：等增益合并，最大比合并和选择性合并(MATLAB simulation rake receiver, divided three ways: equal gain combining, maximum ratio combining and selective merge)

说明：  在机车车辆动力学中，用matlab获得轮轨接触点(get the contact point of wheel and rail )

一群算法的matlab仿真分析，有利于刚接触一群算法的同学进行学习(Ant colony algorithm)

用传输矩阵法解一维光子晶体能带，透过率，以及群速度方向问题，概念清晰，自己编写的，应该比较容易看懂。(the transmission matrix method for one-dimensional photonic crystal, whose parameters are from the paper "negative refraction in one dimensional photonic crystal without negative refractive index material" IJMOT, 2010,5(4))
