/*! \mainpage SuperLU Documentation
|

|
|
||
|
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 perform an LU decomposition with
|
||
|
partial pivoting and triangular system solves through forward and back
|
||
|
substitution. The library also provides threshold-based ILU factorization
|
||
|
preconditioners.
|
||
|
|
||
|
The 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.
