WebSep 16, 2024 · If the algorithm provides an inverse for the original matrix, it is always possible to check your answer. To do so, use the method demonstrated in Example 2.6.1. Check that the products \(AA^{-1}\) and \(A^{-1}A\) both equal the identity matrix. Through this method, you can always be sure that you have calculated \(A^{-1}\) properly!
