Modification of known Gauss method for pivot element elimination that uses internal rows-transposition-vector and works with matrix strictly "col-by-col". The algorithm factorizes the source matrix so that created factor-matrix may be used several tim...
Fortran 77 routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.
A collection of Fortran subroutines that analyze and solve linear equations and linear least-squares problems. The package solves linear systems whose matrices are general, banded, symmetric indefinite, symmetric positive definite, triangular, and tri...
