牛顿法是一种在实数域和复数域上近似求解方程的方法。方法使用函数f (x)的泰勒级数的前面几项来寻找方程f (x) = 0的根。牛顿法最大的特点就在于它的收敛速度很快。(The Newton method is a method to approximate the equation in the real and complex domain. The method uses the first few of the Taylor series of the function f (x) to find the root of the equation f (x) = 0. The biggest characteristic of the Newton method is that its convergence speed is very fast.)
