Smw formula
Web18 Jul 2024 · In general, a matrix has a special form if the number of features (nF) is much less than the number of samples (nS), i.e., \(nS \gg nF\), and in this case the inverse matrix can be inverted by inverting a smaller \(nF \times nF\) matrix by using the Sherman–Morrison–Woodbury (SMW) formula. Therefore, in this paper, to reduce the … WebThe SMW formula (1) is valid only if the matrices A 1 *1and G ZAY−−+ are invertible.

WebThe SMW formula is still employed but at the matrix level, with great advantages both in terms of memory consumption and computational costs. A possibly first description of a general procedure that avoids the Kronecker product in the symmetric case can be found in Reference 31. In there, however, there is no explicit derivation of the SMW ... Web15 Sep 2024 · The SMW formula can convert the problem of solving the original linear system to solving a Lyapunov matrix equation or a cascade of two Lyapunov matrix equations. The simplified problem can be solved efficiently using the ADI method and the bi-conjugate-gradient technique. However, the SMW formula (1.1) is invalid when A is not …
