SuperLU (Version 3.0)
|
|
=====================
|
|
|
|
SuperLU is a general purpose library for the direct solution of large,
|
|
sparse, nonsymmetric systems of linear equations on high performance
|
|
machines. The library is written in C and is callable from either C or
|
|
Fortran. The library routines will perform an LU decomposition with
|
|
partial pivoting and triangular system solves through forward and back
|
|
substitution. The LU factorization routines can handle non-square matrices
|
|
but the triangular solves are performed only for square matrices. The
|
|
matrix columns may be preordered (before factorization) either through
|
|
library or user supplied routines. This preordering for sparsity is
|
|
completely separate from the factorization. Working precision iterative
|
|
refinement subroutines are provided for improved backward stability.
|
|
Routines are also provided to equilibrate the system, estimate the
|
|
condition number, calculate the relative backward error, and estimate
|
|
error bounds for the refined solutions.
