摘要
先扼要介绍列初等变换求可逆矩阵的逆的方法 ,然后着重介绍行初等变换、列初等变换的混合使用同样可以求逆矩阵的逆 。
At first,the writer introdues briefly the way of evaluating invertible matrix's inverse with column elementary transformation,then emphatically introduces the other way of evaluating invertible matrix's inverse mixed use of line elementary transformation,column elementary transformation,and can solve the invertible matrix's linear equations of matrix of coefficients.
