Résumé
We consider a new Steffensen-like iterative method with better applicability than the classical Steffensen method. We analyse the semilocal convergence of this method by means of the majorant principle of Kantorovich. We see that the convergence conditions considered are reduced to the conditions usually imposed on the classical Steffensen method when the new method is reduced to the classical Steffensen method. © Civil-Comp Press, 2014.
