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 with their transposes in the single/double
|
|
precision versions). Iterative refinement, with sparse backward error
|
|
estimates, can be performed. Single and double precision, complex, and
|
|
complex double precision (complex*16) routines are available. (Note that
|
|
complex*16 is not ANSI Fortran-77, but is a common extension to it).
