Sekundarni naslov: | Schur complement |
Sekundarni povzetek: | We define the Schur complement on a block matrix over real numbers. Motivation for the definition comes from the system of linear equations which can be reduced to a smaller system of linear equations by using the Schur complement. We write the inverse matrix which blocks are expressed by Schur complement. Those equalities were established already in 1939 by mathematician Aitken. We prove the quotient property of nested Schur complement. We also investigate the properties of determinants using Schur complement. We develop some properties of positive semidefiniteness of Schur complement of a symmetric matrix. We use Schur complement to construct the Cholesky decomposition of a symmetric positive definite matrix. |
