摘要
求逆矩阵是线性代数课程中很重要的教学内容之一,大部分教材中的方法:一是用伴随矩阵来求逆矩阵,二是用初等行变换求逆矩阵,本文从另外角度又介绍了两种求逆矩阵的方法,并通过例题给予说明,这对于求逆矩阵的教学和拓展学生视野具有一定的借鉴作用.
How to solve the inverse matrix is one of the important contents of the linear algebra course.one of the methods is using the adjoint matrix,the other is to use the elementary row transformation of matrix inversion.In the paper,we use the two other kinds of methods to solve the inverse matrix,and give instructions through some examples.It expands the horizons of the readers.
