This document shows in a simple way the near field of a dipole.You can choose the length of it.furthermore if anyone ask about this problem,please send a comment.

2007年全国大学生数学建模获奖论文所需程序代码，其中有较详细的matlab编程，应该有些用处吧(Mathematical Contest in Modeling 2007, papers required for award-winning code, including more detailed matlab programming, it should be of some use)

说明：  基于MATLAB的一个电力系统潮流分析程序，效果不错(A MATLAB-based power flow analysis program, good results)

这个程序关于语音消噪，实现了一个基于最小均方误差算法的二阶自适应噪声对消器(This program concerning speech denoising achieve a minimum mean square error algorithm based on second-order adaptive noise cancellation)

本matlab程序的功能是利用人工神经网进行故障模式识别(Fault recognition using ANN)
