摘要
矩阵的初等变换在线性代数中起着举足轻重的作用,本文基于行、列阶梯形矩阵研究矩阵的初等行、列变换,并多角度、多解法举例探索初等变换在求矩阵的秩、求逆矩阵、解矩阵方程及求解线性方程组等中的应用。
The elementary transformation of matrix plays an important role in linear algebra.This paper studies the elementary row and column transformation of matrix on the basis of row and column stepped matrix,and explores the application of elementary transformation in the rank of matrix,inverse matrix,solving matrix equations and solving linear equations with multi-angle and multi-solution examples.
