摘要
介绍了高阶矩阵逆矩阵的几种不同求法,并通过具体的例题从定性与定量两个方面进行了论证,同时在分块矩阵中得到了更一般形式的逆矩阵的计算公式,将有助于教师的教学与学生的学习.
This paper introduces several different methods to solve the inverse matrix of higher-order matrix,demonstrates it qualitatively and quantitatively through specific examples,meanwhile,more general calculation formulas of inverse matrix is obtained in block matrix,which will help teaching and learning.
