Optimal Fourth-Order Weerakoon–Fernando-Type Methods for Multiple Roots and Their Dynamics
(Mediterranean Journal of Mathematics, 2019-04-16)
In this paper, we present optimal fourth-order methods for finding multiple roots of non-linear equations, where the multiplicity is known in advance. These methods are based on the third-order method given by Weerakoon ...
On the design and analysis of high order Weerakoon-Fernando methods based on weight functions
(Computational and Mathematical Methods, 2020-06-18)
In this article, using the idea of weight functions on Weerakoon‐Fernando's method, an optimal fourth‐order method and some higher order multipoint methods for solving nonlinear equations are proposed. These methods are ...
