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! When an LDU factorization exists and is unique, there is a closed (explicit) formula for the elements of L, D, and U in terms of ratios of determinants of certain submatrices of the original matrix A. In particular, , and for , is the ratio of the -th principal submatrix to the -th principal submatrix. Computation of the determinants is computationally expensive, so this explicit formula is not used in practice. is manhattan its own city
