Abstract

In this paper, seventh-order iterative methods for the solution of
nonlinear equations are presented. The new iterative methods are developed by
using weight function method and using an approximation for the last derivative,
which reduces the required number of functional evaluations per step. Several
examples are given to illustrate the eciency and the performance of the new
iterative methods.
