Inverse of a matrix: If A and B are two square matrices such that AB = BA = I, then B is the inverse matrix of A. Inverse of matrix A is denoted by A –1 and A is the inverse of B. Inverse of a square matrix, if it exists, is always unique. My answer is : D= BA-2 B-1 A-1 CA 2 (B T)-1 C 2. In this paper we will prove several matrix equations involving generalized Vandermonde matrices, which give explicit algebraic infor- mation about the inverse matrices. . If no B exists then A is said to be singular (has no inverse). Then, Matrices A and B are inverse … Formula for 2x2 inverse. Send article to Kindle.
