摘要
提出了求一元方程实根的两种单点迭代法,证明了他们的局部收敛性,并且证明了他们是至少三阶收敛的,据此构造了一个至少三阶收敛的迭代函数族。
This paper introduces some of the iterative methods for solving equations of one variable, and proves that these iterative methods have local convergence and third order convergence at least on the basis of which an iterative function family is formed.
