matlab语言写的计算八木天线的程序，可以改变单元的数量，给出各个阵子的电流分布和方向图 (matlab language computing Yagi antenna program, you can change the number of units each time around given the current distribution and orientation map)

本程序是基于非等距节点的正交多项式的最小二乘法拟合算法，该算法已经在vc++6.0下调试通过，经多次验证，本算法的拟合误差较小。(This procedure is based on equidistant nodes of non-orthogonal polynomial least squares fit algorithm, which has been in vc++6.0 through debugging, after repeated verification, the algorithm of fitting error is small.)

计算多材料单元平均应力应变,用于提取计算等效弹性模量 泊松系数(Calculate the average stress-strain of multi-material elements)

频谱分析,用于对等时间间距的序列进行频谱分析 很好的(Spectrum analysis for equivalent time interval sequence spectrum analysis is very good)

QR分解法是目前求一般矩阵全部特征值的最有效并广泛应用的方法，一般矩阵先经过正交相似变化成为Hessenberg矩阵，然后再应用QR方法求特征值和特征向量。它是将矩阵分解成一个正规正交矩阵Q与上三角形矩阵R，所以称为QR分解法,(QR decomposition )

matlab的adi方法求解偏微分方程，精确度较高(ADI method of MATLAB for solving partial differential equations)
