How do we determine whether a matrix has an inverse?

Web3.1.1 The left inverse and right inverse. The usual matrix inverse is defined as a two-side inverse, i.e., AA−1 = I = A−1A because we can multiply the inverse matrix from the left or from the right of matrix A and we still get the identity matrix. This property is only true for a square matrix A. WebIf no such matrix exists, then M is said to be a singular matrix.
