WebTo compute a matrix inverse using this method, an augmented matrix is first created with the left side being the matrix to invert and the right side being the identity matrix. Then, Gaussian elimination is used to convert the left side into the identity matrix, which causes the right side to become the inverse of the input matrix. WebThe inverse of a matrix can be calculated by following the given steps: Step 1: Calculate the minors of all elements of A. Step 2: Then compute the cofactors of all elements and write …
