任意初等行列混合变换求解线性方程组

摘要

提出一种任意施行初等行列混合变换求解线性方程组的新方法，分两种情形：1．系数矩阵为可逆矩阵；2．系数矩阵为一般m×n矩阵，两种方法都简便易行。%This paper gives a new method to solve the system of linear equations with elementary row and column trans formation, and discuss two cases： 1. Coefficient matrixes are invertible; 2. Cofficient matrixes are general m x n matri- xes. This method is easy to operate and the conclusion is significant.
