Fifth-order iterative method for finding multiple roots of nonlinear equations. (English) Zbl 1222.65047

Numer. Algorithms 57, No. 3, 389-398 (2011).
The authors propose a modification of Newton’s method based on some existing modified Newton’s methods to find multiple roots of nonlinear equations with unknown multiplicity. The fifth-order convergence of the method is established. Some numerical results are presented to show that the proposed method is more efficient than the classical Newton’s method and some other existing methods.
