WebOne can show that all linear systems of equations with a square nonsingular matrix can be solved by Gaussian elimination with pivoting, or equivalently, by LU-factorization with pivoting. The factor L is not lower triangular when pivoting is employed. Example 1. The function lu in MATLAB and Octave determines the LU-factorization of a matrix A with WebCreate a matrix decomposition object for a 25-by-25 Hilbert coefficient matrix and then check to see whether the underlying coefficient matrix is ill conditioned.
