In this article, we propose a new family of methods, such as Jarratt, with the fifth and sixth order. This includes some popular methods as special cases. We propose four different selection for parameter matrix . The main advantage of the proposed methods is that they work well for any value of parameter “” in the first stage of iterations, while the existing methods work only for some . Thus, we extend essentially the domain of applicability of the original ones. Based on the computational efficiency analysis, we also made a selection of some high-efficiency ones among the families.

在本文中,我们提出了一种新的方法系列,例如Jarratt,具有第五和第六个顺序。这包括一些流行的方法作为特殊情况。我们为参数矩阵提出了四种不同的选择。提出的方法的主要优点是,它们对于参数“在迭代的第一阶段,而现有方法仅适用于某些 。因此,我们实质上扩展了原始方法的适用范围。在计算效率分析的基础上,我们还选择了一些高效率的家庭。
