Abstract

We have modified our previously developed fourth order method to approximate solution of systems of equations including non-differentiable ones. The most recent article by Kumar et al. (Numer. Algor. 86:1051–1070, 2021) compared fourth order and seventh order methods to show the efficiency of their fourth order. We have shown that our method compares favorably with methods in the literature.

求解方程组的一种有效的无导数方法

摘要

我们已经修改了我们之前开发的四阶方法来近似方程组的解，包括不可微的方程组。Kumar 等人的最新文章。(Numer. Algor. 86:1051–1070, 2021) 比较了四阶和七阶方法以显示其四阶的效率。我们已经表明，我们的方法与文献中的方法相比具有优势。
