摘要
给出了牛顿迭代法的两种修正形式,证明了它们是三阶收敛的,数值实验表明,与其它已知的三阶收敛的牛顿迭代法相比,修正的牛顿迭代法具有一定的优势.
Two variants of Newton＇s Iteration method are given. The orders of convergence of the variant methods are three. In the end, numerical tests show that the variant methods have some more advantages than the other known Newton＇s Iteration methods with third- order convergence.
