说明：  研究舍入误差的例程，可以帮助初学计算方法的人。(Of rounding error in the routine that can help beginners who calculation.)

三维 近场－远场 变换 FDTD...........(FDTD near field to far field transmition)

说明：  c语言编写的高效用LU分解法求任意维数的矩阵的逆，它是经典书籍《算法导论》（第二版）中矩阵求逆的c语言实现。 (The algorithm of matrix inverse is based on LU decomposition which is proposed by the book of introduction to algorithm (second edition).)

说明：  牛顿法又称牛顿-拉弗森方法（Newton-Raphson method），是一种在实数域和复数域上近似求解方程的方法。本程序收敛速度快，迭代步数可取大一些(Newton method, also known as Newton-Raphson method, is an approximate method for solving equations in real and complex fields. The program has fast convergence speed so the number of iteration steps can be larger.)

采用递推最小二乘法在时域范围内辨识传递函数(Recursive least squares method identification in the time domain transfer function)

说明：  使用牛顿迭代法求解非线性方程组，程序简单易懂，初学者都能看明白。(Newton iterative method is used to solve the nonlinear equations. The program is simple and easy to understand for beginners.)
