非齐次线性方程组存在全非零解的充要条件

Prerequisites for the All-Nonzero Solutions to Inhomogeneous Linear Equations

在线性方程组有解判别定理的基础上,给出了一个判定非齐次线性方程组存在全非零解的方法.

On the basis of the solution identification theorem in linear equations,a method is presented to ascertain whether there exists all-nonzero solutions to an inhomogeneous linear equation.
