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. +</longdescription> +</pkgmetadata> |
