matlab的图像教程，很好的资料，有很多例子(matlab image tutorial, good information, there are many examples)

circular shifting property of dft in one dimension

filter data in Matlab

线性系统理论中用到的simulink模型搭建，初级。(Linear system theory simulink model used in construction, primary.)

基于MATLAB_SIMULINK的QDPSK通信系统仿真(MATLAB_SIMULINK QDPSK communication system simulation)

说明：  主成分分析法，用于将低数据维度，减小有相关性的数据特征。(dimensionality reduction)

PCA与不用PCA进行人脸识别的比较，请先安装sltoolbox，人脸数据库采用orl(PCA and PCA for face recognition do not have the comparison, please install sltoolbox, face database used orl)

1/3 oct filter code,used for frequency analysis(1/3oct matlab code,used for frequency analysis)

说明：  Matlab编程练习题集,非常适合初学者(matlab practise examples)

自己做的高压直流输电的半边模型，采用定电流控制。在普通12脉波高压直流输电的基础上，替换b、c相的变压器为移相变压器，消除了11、13次谐波。(HVDC own half model, using the constant current control. On the basis of the normal 12-pulse HVDC, replacing b, C-phase transformer for the phase-shifting transformer, eliminating 11,13 harmonics.)
