UMFPACK

Abstract

UMFPACK Version 2.2 is a package for solving systems of sparse linear systems, Ax=b, where A is sparse and can be unsymmetric. It is written in ANSI Fortran 77. There are options for choosing a good pivot order, factorizing a subsequent matrix with the same pivot order and nonzero pattern as a previously factorized matrix, and solving systems of linear equations with the factors (with A, L, or U, or their transposes). Iterative refinement, with sparse backward error estimates, can be performed. Both single and double precision routines are available.
