计算太阳黑子的活动周期，分别利用周期图法，Lenvinson-Durbin法和Burg法求得其功率谱，并画出曲线，观察得到活动周期(Calculation of sunspot activity cycle, namely the use of periodogram, Lenvinson-Durbin and Burg obtained the power spectrum, and draw curve, observation cycle)

MATLAB讲座：介面介绍，基础命令，常用数学函数，常用语句等(MATLAB Lecture: Interface description, basic commands, common mathematical functions, common statements, etc.)

对从金属棒材中提取的超声缺陷信号经过自适应滤波以后的极坐标显示图(polar graph of ultrasonic defect signal)

自己做出来的simulink例子，对理解汽车四轮转向很有好处。用到了LOR控制。(Make up their own examples of simulink, to understand the automobile four-wheel steering is very good.Used to control LOR.)

此为一个跟踪前车的matlab仿真模型，其中包括了跟踪算法，和车辆2自由度模型。仿真结果表明可行。(This is a track the vehicle in front of the matlab simulation model, including the tracking algorithm, and the two degrees of freedom model of vehicle. Simulation results show that the feasible.)

最优化算法中的对角二阶拟柯西法的源码，matlab编程实现，希望对大家有用。(Optimization algorithm proposed Cauchy method of source angular second Matlab programming, and hope to be useful.)

利用hough变换检测直线的matlab实现，希望对初学者有用.(Detection using hough transform matlab linear realize, I hope useful for beginners.)

利用Matlab编程实现主成分分析,从数学角度来看，这是一种降维处理技术(Using Matlab programming principal component analysis, from a mathematical point of view, this is a dimension reduction process technology)
