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 are invertible, then is invertible and. Proof. There is an analogous proposition for the Schur complement of . You may try to prove it as an exercise and then use the ...

The Schur complement arises when performing a block Gaussian elimination on the matrix M. In order to eliminate the elements below the block diagonal, one multiplies the matrix M by a block lower triangular matrix on the right as follows: Continuing the elimination process beyond this point (i.e., … Ver mais In linear algebra and the theory of matrices, the Schur complement of a block matrix is defined as follows. Suppose p, q are nonnegative integers, and suppose A, B, C, D are respectively p × p, p × q, q × p, … Ver mais The Schur complement arises naturally in solving a system of linear equations such as Assuming that the submatrix $${\displaystyle A}$$ is invertible, we can eliminate Ver mais • If p and q are both 1 (i.e., A, B, C and D are all scalars), we get the familiar formula for the inverse of a 2-by-2 matrix: • In … Ver mais • Woodbury matrix identity • Quasi-Newton method • Haynsworth inertia additivity formula Ver mais WebIn numerical analysis, the Schur complement method, named after Issai Schur, is the basic and the earliest version of non-overlapping domain decomposition method, also … cable in buffalo mn
