摘要:
本文从讨论矩阵A的逆矩阵A-1非负的条件出发,研究用离散方程组求解微分方程数值近似解不出负的条件,并列举出一些类型的离散方程组是能满足这些条件。
Abstract:
In solving differential equation by means of discrete equations, the nonnegativity conditions of numerical approximate solution are studied and some types of discrete equations which will satisfy the condition are enumerated. The study starts from a discu
