说明：  《系统辨识和matlab仿真》，配套源码( System Identification and matlab simulation , supporting source code)

QUIVERS(x,y,u,v,Gscale,Spos,Sunit) plots velocity vectors as arrows with components (u,v) at the points (x,y). The matrices X,Y,U,V must all be the same size and contain corresponding position and velocity components (X and Y can also be vectors to specify a uniform grid).

fisher变换可以将 维空间的样本投影到一条直线上，形成一维空间，这个就是用matlab解决fisher的例题(the fisher transform a sample-dimensional space can be projected onto a straight line, forming a one-dimensional space, this is solved with matlab fisher Example)

说明：  用二进制遗传算法做特征选择，此算法效率高，选择的特征数目少。(The binary genetic algorithm is used for feature selection, which has high efficiency and few features.)

Stereovision reconstruction using Triangulation and "Mire" Calibration. Implemented in Matlab language

计算无线通信网络的效用值。采用s型函数，具备2个可调参数，分别控制中值和弹性。(The calculation of the wireless communication network utility value. S function, with two adjustable parameters, respectively, to control the value and flexibility.)

高斯信道下BPSK信号的编码和译码，带有完整的说明(Gaussian channel under BPSK signal encoding and decoding, with complete instructions)

通过幅相误差存在的情况下MUSIC谱峰与未存在幅相误差时的比较，可以看出幅相误差对DOA估计还是有很大的影响。此程序中加入的幅相误差参数服从高斯分布(Through the case of amplitude and phase errors exist MUSIC peaks when compared with the amplitude and phase error does not exist, it can be seen amplitude and phase errors have a lot of influence on DOA estimates. Amplitude and phase errors of the parameters of this program by adding Gaussian distribution)

Facial Feature Extraction matlab code

MatLabV1.0最初的matlab版本，大家可以试着玩玩！(MatLabV1.0 initial version of Matlab, we can try to play!)
