WebApr 3, 2024 · Invertible matrices have the following properties: 1. If M is invertible, then M−1 is also invertible, and ( M−1) −1 = M. 2. If M and N are invertible matrices, then MN is invertible and ( MN) −1 = M−1N−1. 3. If M is invertible, then its transpose MT (that is, the rows and columns of the matrix are switched) has the property ( MT) −1 = (M−1) T. WebThe pseudo-inverse of a matrix is a matrix that generalizes to arbitrary matrices the notion of inverse of a square, invertible matrix.
