牛顿迭代法（Newton s method）又称为牛顿-拉夫逊（拉弗森）方法（Newton-Raphson method），它是牛顿在17世纪提出的一种在实数域和复数域上近似求解方程的方法。-Newton iterative method (Newton' s method), also known as the Newton- Raphson (Raphson) method (Newton-Raphson method), it is a method proposed by Newton in the 17th century in the field of real numbers and complex field approximation for solving equations.
