Higher order Jarratt-like iterations for solving systems of nonlinear equations

作者:

Highlights:

• The main advantage of the proposed methods is that they work well for any value of parameter “a” in the first stage of iterations, while the existing Jarratt-like methods work only for some a=2/3, 1/2.

• To develop new methods with the highest possible order of convergence which requires the smallest possible evaluation of the function F and its derivatives and matrix inversions.

• To extend the domain of applicability of existing methods.

• From numerical results, clearly show that proposed method with the selected parameters are faster than other cases.
