matlab绘图的一个程序，程序不是很长 但比较经典 (very good)

matlab中的数值微分，有用中点公式，自适应法，理查森外推算法等方法求函数的导数，算法的程序实现在文件中都已经给出了。(in the numerical differentiation matlab, useful midpoint formula, adaptive method, Richardson extrapolation methods such as France seek the derivative of the function, the algorithm of the program implementation in the document have been given.)

在这个更新的代码，新功能，包括colorbar，samesize包括向量plottting... ％更新版本$日期：5月18日，2011年由梁枯盎斯蒂文斯技术学院 ％更新1：更改int8到Int16的colormap的是，当电流超过64个大，这将导致错误 ％更新2：加入 samesize 为使所有的向量samesize ％更新3：添加colorbar相应的开方的幅度（ü^2+ V键^ 2） ％更新4：错误修复，当你为h = quiverc，这是行不通的。 ------------------------------------------------- ----------- (In this updated code,new features including colorbar, samesize vectors plottting are included Updated version $Date: May 18th,2011 by Liang Kuang at Stevens Institute of Tech Update 1: Change int8 to int16 when current colormap is bigger than 64,which will cause error Update 2: Added samesize for making all the vectors the samesize Update 3: Add colorbar corresponding the the magnitude of sqrt(u^2+v^2) Update 4: bug fixed,when you do h=quiverc, it doesn t work. ------------------------------------------------------------)

FBG反射谱，要用的人会非常需要，需要的人可以看看，很不错的(FBG id1=fopen( lambdaCMT.txt , wt ) fid2=fopen( rhoCMT.txt , wt ) f1=inline( -i.*delta.*y1-k.*y2 , t , lambda , wk , delta , k , y1 , y2 ) f2=inline( -k.*y1+i.*delta.*y2 , t , lambda , wk , delta , k , y1 , y2 ) lambda=1547 while lambda<1552 t0=-501426 h=2.0057e+003 n=500 y1=1 y2=0 )

the file is the algorithm used for the color based seganography with multiple compression algorithms

solves 1d linear wave eq. by 4th order 13 point DRP scheme

可以实现旋转和平移图像的拼接，简单而实用。(Can achieve rotation and translation image stitching, simple and practical.)

模糊PID调节，并且通过与普通PID调节对比得出较好的效果(Fuzzy PID control, and by contrast with the ordinary PID regulator obtained better results)
