利用matlab编写程序，通过时域有限差分方法进行电磁场的数值模拟(Use matlab, numerical simulation of electromagnetic fields by the finite difference time domain method)

用于计算二维相关光谱，P为同步二维相关光谱，Q为异步二维相关光谱； % data为m*n的光谱m为波长点数，n为样品数；(Two dimensional correlation spectroscopy)

利用matlab的gui设计的带有输入和输出功能的界面图形，实现等距线可视性很强，自己独立编写的数据和图形，学习非常值得,实现pca svm压缩图像，matlab语言(Using GUI of MATLAB to design interface graphics with input and output functions, realizing the visibility of isometric line is very strong, the data and graphics written independently by oneself are very worthwhile to learn, and realizing PCA SVM compressed image, MATLAB language)

matlab中文帮助文档，文档为HTML帮助文档格式。通过中文简要介绍了MATLAB的使用方法。(Chinese matlab help document, document, document formats HTML Help. By Chinese brief introduction to the use of MATLAB.)

在matlab环境下，用simulink模块编程实现PID控制基本算法(In the matlab environment, using simulink module programming PID control of the basic algorithm)

说明：  这是小波神经网络的MATLAB6.5下的程序,不算完善,大家一起研究吧(WNN Matlab6.5 the procedure is not perfect, it all together)

m序列产生子函数 gold序列产生子函数 自相关函数和互相关函数计算子函数 调用子函数[s,k,pn]=m(c,b0)产生第二条m序列(function [Rm]=Rm(golda,goldb) 自相关函数和互相关函数计算子函数 N=11 n=2^N-1 Rm(1)=sum(golda.*goldb)/n for k=1:n-1 Rm(k+1)=sum(golda.*circshift(goldb,[0,k]))/n end Rm )

Some algorithms of variable step size LMS adaptive filtering are studied．The VS—LMS algorithm is improved． Another new non-linear function between肛and e(／ t)is established．The theoretic analysis and computer simulation results show that this algorithm converges more quickly than the origina1．Furthermore，better antinoise property is exhibited under Low—SNR environment than the original one．(variable step size of a LMS daptive filtering are studied. The VS-LMS algorithm is improved. Another new non-linear function between anus and e (/ t) is established.
