METODE ITERASI BARU BEBAS DERIVATIF UNTUK MENEMUKAN SOLUSI PERSAMAAN NONLINEAR

Abstract

This article discusses a new derivative-free iterative method to find the solutions of nonlinear equations. Analytically it is shown that the order of convergence of the method is two. The advantage of this iterative method is that it can be used to obtain real roots and complex roots. In terms of this ability, the method is equivalent
to Muller’s method. Numerical tests show that the iterative method is superior and efficient in terms of the number of iterations required to obtain a root.
