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.
