A modified Newton-Jarratt’s composition. (English) Zbl 1251.65074

Summary: A reduced composition technique is used on Newton and Jarratt’s methods in order to obtain an optimal relation between convergence order, functional evaluations and number of operations. Following this aim, a family of methods is obtained whose efficiency indices are proved to be better for systems of nonlinear equations.
