Examine why solving a linear system by inverting the matrix using invab is inferior to solving it directly using the backslash operator, x a\b create a random matrix a of order 500 that is constructed so that its condition number, conda, is 1e10, and its norm, norma, is 1. You clicked a link that corresponds to this matlab command. In fact, the determinant of a should be exactly zero. For example, det can produce a largemagnitude determinant for a singular matrix, even though it should have a magnitude of 0. It then uses the results to form a linear system whose solution is the matrix inverse inv x.
