where A, U, C and V all denote matrices of the correct size. Specifically, A … The nice thing is we don't need the Matrix Inversion Lemma (Woodbury Matrix Identity) for the Sequential Form of the Linear Least Squares but we can do with a special case of it called Sherman Morrison Formula: (A + u v T) − 1 = A − 1 − A − 1 u v T A − 1 1 + v T A − 1 u 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 for Infinite Matrices. Assume all matrices are real. Suppose A is a positive definite matrix of size n \times n, while H is a \infty \times n matrix and D is an infinite matrix with a diagonal structure, that is only nonzeros on the diagonals, i.e.

The Matrix Inversion Lemma goes as: ( A + U C V) − 1 = A − 1 − A − 1 U ( C − 1 + V A − 1 U) − 1 V A − 1. Deriving it is by utilizing these useful identities: (1) U + U C V A − 1 U = U C ( C − 1 + V A − 1 U) = ( A + U C V) A − 1 U (2) ( A + U C V) − 1 U C = A − 1 U ( C − 1 + V A − 1 U) − 1. 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 - special case If C is also invertible, from (5): (A +BCD)−1 = A−1 −A−1B(I +CDA−1B)−1CDA−1 = A−1 −A−1B(C−1 +DA−1B)−1DA−1 (9) which is a commonly used variant (for example applicable to the Kalman Filter covariance, in the ‘correction’ step of the filter). Answer to 10.13 Verify (10.32) and (10.33) by using the matrix inversion lemma.

Assume all matrices are real. Suppose A is a positive definite matrix of size n \times n, while H is a \infty \times n matrix and D is an infinite matrix with a diagonal structure, that is only nonzeros on the diagonals, i.e. size \infty \times \infty.
