PID控制的应用实例例程（本资料有两本分组成）(PID control application example routines (there are two sub-components of the data) )

包括脚本文件和函数文件形式，包括调制，解调，信噪比计算，针对EMD方法的不足。( Including script files and function files in the form, Includes the modulation, demodulation, signal to noise ratio calculation, For lack of EMD.)

一本的电磁数值分析方面的，集有限差分法，有限元法和矩量法为一体的基础教材。(An electromagnetic numerical analysis, set finite difference method, finite element method and the method of moments as one basis for teaching materials.)

此为，计算地震信号频谱的MATLAB程序，效果较好。可以看到不同道数的频谱(This is calculated seismic signal spectrum MATLAB program is better. Can see that the number of different spectrum Road)

三相桥式整流电路，可以直接用，matlab编写(Three-phase bridge rectifier circuit can be directly used, matlab prepared)

谱聚类的matlab实现，其中包括k-means的实现，谱聚类聚类结果要优于k-means的聚类结果(Spectral clustering matlab code, including the code of k-means, spectral clustering results is better than k-means clustering results)

the graph of x=0.2*(1.2^n)

在ar人脸库上实现Direct Fisher discriminant analysis,该方法首先对类内散布矩阵对角化，然后对类间散布矩阵对角化，使类间散布矩阵对角化的矩阵即使鉴别向量集(In the ar face database to achieve Direct Fisher discriminant analysis, this method first within-class scatter matrix diagonalization, and then between-class scatter matrix diagonalization, so that between-class scatter matrix diagonalization of the matrix even if the identification of a vector set)

说明：  基本的图像处理技术在MATLAB里得到非常好的应用(The basic image processing technology in the years to be a very good application of MATLAB)
