摘要
给出了两类牛顿迭代法的修正形式,证明了这两类迭代格式至少是三阶收敛的,数值实验表明,与其它已知的三阶收敛的牛顿迭代格式相比,新迭代格式具有一定的优势.
Two classes of Newton's variants Iteration method are given.The orders of convergence of the variant methods are three at least.Numerical tests show that the variant methods have more advantages than the other known Newton's Iteration methods with third-order convergence.
