摘要
阐述了用4块矩阵法求非奇异方阵逆阵的理论,给出了非奇异方阵化为不同形式的4块矩阵时各自逆阵相应的简化计算公式。
This paper first describes the theory of deriving inverse matrix of non-singular sqare matrix using four block matrix method, then presents the simplified reduction formula corresponding with each inverse matrix when non-singular squre matrix is changed into different types of four block matrix.
