正线性方程组正解判别的两个结果

Two Results of the Discrimination of A Positive Solution for Positive Linear System

非齐次线性方程组在科学计算和日常生活中会经常出现的,在研究实际问题中也会接触系数和右端项皆为正的方程组,而研究它有正解更有实际意义.对正线性方程组给出了合理的变形,对其正解的判别给出了若干方法,得到一些重要结果.

In this paper, the positive linear system is rationally transformed, some new conditions are given for the existence of a positive solution for positive linear system.
