WebMatrix inversion identity We give the matrix inversion inequality that extracts the inversion of A+BCD : and provide two proofs. proof one: using the Schur's Complement. This is a simple trick, and can be verified by doing the same procedure of row-col transformation on M using D instead of A , and compare the inversion under the two forms. WebOther inversion methods tend to produce a matrix that is either a left inverse or a right inverse but not both. A good example is Newton’s method. If one iterates with V(t) = (2I V(t 1)A)V(t 1) then V(t) converges to a left inverse. If one iterates with V(t) = V(t 1)(2I AV(t 1)) then V(t) converges to a right inverse. Strassen’s inversion ...
