摘要
本研究考虑分块矩阵在加法以及幂运算下的广义Schur补的秩的性质.再结合广义约束逆理论知识,得到了分块矩阵在广义Schur补下和与幂的秩的性质.
In this paper,we consider the properties of the rank of generalized Schur complement of block matrix in the addition and exponentiation of matrix.By combining with the knowledge of generalized constrained inverse theory,we obtain the properties of the rank of block matrix under generalized Schur complement and the rank of exponentiation.
