Abstract
In this note we make a comparative study of the convergence orders for the Steffensen, Aitken and Aitken-Steffensen methods. We provide some conditions ensuring their local convergence. We study the case when the auxiliary operators used have convergence orders \(r_1,r_2 \in \mathbb {N}\) respectively. We show that the Steffensen, Aitken and Aitken-Steffensen methods have the convergence orders \(r_1+1\), \(r_1+r_2\) and \(r_1r_2+r_1\) respectively.
