matlab中几个非常实用的画图程序，分别用来画箭头，方形，球体，多面体，坐标系，非常实用。(matlab drawing on some very practical procedures were used to draw the arrow, square, sphere, polyhedron, coordinate system, very useful.)

说明：  基于MATLAB遗传算法(SGA)实现 基于MATLAB遗传算法(SGA)实现(MATLAB based genetic algorithm (SGA) based on MATLAB genetic algorithm (SGA) to achieve)

应用于MIMO阵列的常规波束形成方法，已经使用多次，正确的。(CBF for MIMO array。)

carlight1中是一个用C编的程序，用于计算每条光线在测试屏上的坐标(carlight 1 is a C series of the program, each ray is used to calculate the coordinates on the screen in the test)

Forward Back algorithm regarding to Hidden Markov Model

用凯瑟窗设计一个数字带通滤波器，设计指标为 低阻带：ws1=0.2pi,as=70dB, 低通带：wp1=0.35pi,ap=1dB, 高通带：wp2=0.65pi,ap=1dB, 高阻带：ws2=0.8pi,as=60dB(Kaiser window design with a digital band-pass filter design specifications for the Low resistivity zone: ws1 = 0.2pi, as = 70dB, Low-pass band: wp1 = 0.35pi, ap = 1dB, High-pass band: wp2 = 0.65pi, ap = 1dB, Impedance with: ws2 = 0.8pi, as = 60dB )

SVM的多分类问题MATLAB工具包。传统的SVM只支持二分类问题，MATLAB自带的工具包也存在同样的问题。可以在setpath中导入此包，便可轻松将SVM问题扩展到多分类的层面。(A matlab toolkit to solving multi-classification problems based on svm. Traditional svm and the matlab toolkit svmtrain can only support for bi-classification problems which could hardly satisfy users requirments. U can import this toolkit by click setpath and can easily do what you like.)

说明：  数字滤波器的设计,用双线性变换设计N阶巴特沃斯低通数字滤波器。(The design of the digital filter, using bilinear transformation design N order butterworth low-pass digital filter.)

本程序由一对m序列优选对模二加生成一组平衡GOLD序列码，用于对直扩系统仿真之中，通过改变第二个m序列的初始状态可以生成不同的GOLD序列码(The program consists of a pair of m sequence optimization of mode two and generate a set of balanced GOLD sequence codes for DSSS system simulation, by changing the initial state of second m sequences can generate GOLD sequence code different)
