this codes is only for education purpose

介绍了matlab里常用的命令函数，便于查找使用。(The matlab command function, easy to find use.)

时频分析方法提供了时间域与频率域的联合分布信息，清楚地描述了信号频率随时间变化的关系。(Time-frequency analysis method provides a time-domain and frequency domain, the joint distribution of information that clearly describes the signal frequency versus time relationships.)

matlab code for path loss model

矢量算法模型 用于逆变器的空间矢量脉冲产生(vetor matlab)

系统辨识课程中经典辨识方法之差分方程辨识源代码(Differential equation )

1、掌握用MATLAB计算拉格朗日、分段线性、三次样条三种插值的方法，改变节点的数目，对三种插值结果进行初步分析。 2、掌握用MATLAB作线性最小二乘的方法。 3、通过实例学习如何用插值方法与拟合方法解决实际问题，注意二者的联系和区别。(1. Grasp by matlab calculating Lagrange, segement linear, 3rd order spline these 3 interpolation method. Analisize the 3 interpolation results by changing the No. of points. 2. Grasp the method of linear minimun 2 product mehtod using matlab. 3. Solve the practical problems though the study of example of how to use interpolation and fitting method. Pay attention to the relation and difference of the 2 methods.)

说明：  实现最小二乘算法进行系统辨识，并给出了图形。(To achieve least-squares algorithm for system identification, and gives the graphics.)
