576

 
MODGE and REFINE: Fortran subroutines for solving an n-by-n system of (possibly
singular) linear algebraic equations. The algorithm consists of Gaussian
elimination combined with a new pivoting strategy which is particularly well
suited to problems where residuals can be made small by solving for fewer than n of
the unknowns. (See I. Barrodale and G.F. Stuart, ACM TOMS 7 (1981) pp. 391-397.).
 
Classes  :  D2a1 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (general real
                 nonsymmetric matrices)
            D9a1 . Least squares (L-2) solution of singular, overdetermined or
                 underdetermined systems of linear equations without
                 constraints
            D9a4 . Other solutions of singular, overdetermined or
                 underdetermined systems of linear equations without
                 constraints
