    METODE ITERASI OPTIMAL TANPA TURUNAN BERDASARKAN BEDA TERBAGI
    (2014-03-25) Amelia, Riski; Putra, Supriadi; Agusni
    We discuss an iterative method free from derivative based on divided difference for solving nonlinear equation. This iterative method has the convergence of order six and for each iteration it requires four function evaluation, so the efficiency index has 1.565. Further more, the computational tes shows that the discussed method superior, both in the number of function evaluations, as well as the number of iterations needed to get a root
