WebTheorem 2.1. Let a 2 D be a simple zero of a sufficiently differentiable function f : D#R ! R for an open interval D, which contains x 0 as an initial approximation of a.Ifx 0 is sufficiently close to a, then the three-step method defined by (7), has fourth- order convergence. Proof. Let a be a simple zero of f. Since f is sufficiently differentiable, by expanding fðx WebJun 1, 2014 · In this paper, an algorithm is proposed to compute the inverse of an invertible matrix.
