通过matlab图形进行欧拉角的演示，对于理解欧拉角有很大的帮助。(Matlab graphics through Euler angle presentation, for understanding the Euler angle has a great help.)

This is program set for SLAM using Matlab and filtering method. This code is fast. It is pretty good for student and teacher to learn. It is also easy to improve based on this code. It is really helpful for the new guy in this area. This is a platform and easy to extend using other filtering methods

用MOM计算V型天线的电流分布、输入阻抗及辐射方向图。其中L=0.3λ，L/a=2000，激励用δ-gap模型。(calculate the current distribution, input impedance and radiate pattern of V-antenna with MOM. L=0.3λ，L/a=2000, δ-gap source)

说明：  该仿真模型是用来提取单机无穷大系统发生故障短路各线路三相电压的最大值(The simulation model is used to extract single machine infinite bus system short-circuit failure of the maximum three-phase voltage of each line)

这是一些MATLAB图形用户设计界面的源程序，对初学着有帮助哦！(which is a MATLAB graphical user interface design of the source of a novice to help!)

x0 = ones(2,2) Make a starting guess at the solution options = optimset( Display , off ) Turn off Display [x,Fval,exitflag] = fsolve(@myfun,x0,options) The solution is x = -0.1291 0.8602 1.2903 1.1612 Fval = 1.0e-009 * -0.1619 0.0776 0.1161 -0.0469 exitflag = 1 and the residual is close to zero. sum(sum(Fval.*Fval)) ans = 4.7915e-020

说明：  相信对初学者比较有用，欢迎大家下载并交流与指导。(Believe that the more useful for beginners, are welcome to download and exchange and guidance.)

This Algorithm comutes demagnetizig tensor from Newell Paper[1] between two rectangular shape elements.Main function is and there is equivallent function written in c-language, you can use it to compile mex file.This script can be used in field of micromagnetics and finite difference magnetic simulation software. 1.
