摘要
本文在各种合理的内向量不同选取下,讨论了一步混合方法的代数稳定性,导出了一步混合方法代数稳定的充要条件。据此,得到了一系列结论。最后,给出了若干一步二阶、三阶代数稳定的混合方法公式。
This paper is concerned with the algebraic stability of one-step hybrid method under the various different choices of internal vector. A sufficient and necessary condition for the algebraic stability of one-step hybrid method is derived. Furthermore, we derive a series of results. we give a number of one-step two-order and three-order hybrid formulae which are algebraically stable in the end.
