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) is also known as Newton- Ralph monson (laffer sen) method (Newton Raphson method), it was proposed by Newton in the 17th century a real number and complex domain on approximate method of solving the equation
