WebMay 24, 2015 · It is shown in On Deriving the Inverse of a Sum of Matrices that ( A + B) − 1 = A − 1 − A − 1 B ( A + B) − 1. This equation cannot be used to calculate ( A + B) − 1, but it is useful for perturbation analysis where B is a perturbation of A. There are several other variations of the above form (see equations (22)- (26) in this paper). WebTo find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). Sometimes there is no inverse at all Multiplying Matrices Determinant of a Matrix Matrix Calculator Algebra Index Data Entry. Enter your matrix in the cells below "A" or "B".
