Then we have. 0.10 matrix inversion lemma (sherman-morrison-woodbury) using the above results for block matrices we can make some substitutions and get the following important results: (A+ XBXT) 1 = A 1 A 1X(B 1 + XTA 1X) 1XTA 1 (10) jA+ XBXTj= jBjjAjjB 1 + XTA 1Xj (11) where A and B are square and invertible matrices but need not be of the Matrix inversion Lemma: If A, C, BCD are nonsingular square matrix (the inverse exists) then [A+BCD] 1 =A 1 A 1B[C 1+DA 1B] 1DA 1 The best way to prove this is to multiply both sides by [A+BCD]. [A+BCD][A 1 A 1B[C 1 +DA 1B] 1DA 1] = I+BCDA 1 B[C 1 +DA 1B] 1DA 1 BCDA 1B[C 1 +DA 1B] 1DA 1 = I+BCDA 1 BCC|{z 1} I [C 1 +DA 1B] 1DA 1 BCDA 1B[C 1 +DA 1B] 1DA 1 = I+BCDA 1 BCfC 1 +DA 1Bg[C 1 +DA 1B] 1 | {z } I DA 1 = I 1 $\begingroup$ Matrix inversion Lemma rule which are given in RLS equations(in most books eg Adaptive Filter Theory,Advance Digital Signal Processing and Noise reduction) are some what different from the standard rule given below.

An effective parallel computation algorithm for the static state estimation of a power system is presented. The algorithm makes use of the matrix inversion lemma and assumes the use of a multiple-instruction-stream multiple-data-stream (MIMD) computer system. topics: Taylor’s theorem quadratic forms Solving dense systems: LU, QR, SVD rank-1 methods, matrix inversion lemma, block elimination. Iterative Methods: depends on CONDITION NUMBER When λ is 1 all time steps are of equal importance but as λ smaller less emphasis is given to older values.

Matrix Inversion Lemma. Let , , and be non-singular square matrices; then General Formula: Matrix Inversion in Block form. Abstract: A generalized form of the matrix inversion lemma is shown which allows particular forms of this lemma to be derived simply. The relationships between this direct method for solving linear matrix equations, lower-diagonal-upper decomposition, and iterative methods such as point-Jacobi and Hotelling's method are established. Matrix Inversion Lemma.
