Right invertible matrix

WebInvertible matrix is also known as a non-singular matrix or nondegenerate matrix. Similarly, on multiplying B with A, we obtain the same identity matrix: It can be concluded here that AB = BA = I. Hence A -1 = B, and B is known as the inverse of A. Similarly, A can also be called an inverse of B, or B -1 = A.
