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 WebThis exercise problem is taken from [1] and was a part of the exercise class for the graduate course on "Optimal and Robust Control" at the Technical Univers...
