%description
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.
