Sixth new family method for solving nonlinear equations
Main Article Content
Abstract
Introduction. In this manuscript, we introduce a new multi-step iterative family designed to solve non linear equations.
Materials and Methods. Furthermore, we highly investigate the analysis of convergence from this new iterative family once the multi-step method was defined. We demonstrated that its order of convergence was 6 and its approximated computational order of convergence was 5.98 in majority of numerical experiments.
Results and Discussion. This family is derived from Newtons scheme, but it includes a ‘’fronzen’’ or weight function to add up a third step. Initially, we used as first iterative method the second order Newtons method with the aim to reduce the number of functional evaluations.
Conclusions. Finally, we chose a set of nonlinear equations from recent investigations with the aim to evaluate its efficacy from the new iterative family verifying the amount of iterations to find the approximate solution of the nonlinear equation in comparison to other already proposed sixth order methods achieving a lower computational cost which allow to be an efficient and novel iterative scheme.
