WebSchur complements play a key role in the inversion of block matrices. Proposition Let be a block matrix such that its blocks and are square matrices. If and its Schur complement … WebBased on the Schur complement, some upper bounds for the infinity norm of the inverse of generalized doubly strictly diagonally dominant matrices are obtained. In addition, it is shown that the new bound improves the previous bounds. Numerical examples are given to illustrate our results. By using the infinity norm bound, a lower bound for the smallest …
