| -pc_lu_reuse_ordering | - Activate PCLUSetReuseOrdering()
|
| -pc_lu_reuse_fill | - Activates PCLUSetReuseFill()
|
| -pc_lu_fill <fill> | - Sets fill amount
|
| -pc_lu_damping <damping> | - Sets damping amount
|
| -pc_lu_in_place | - Activates in-place factorization
|
| -pc_lu_mat_ordering_type <nd,rcm,...> | - Sets ordering routine
|
| -pc_lu_pivoting <dtcol> | - - -pc_lu_pivot_in_blocks <true,false> - allow pivoting within the small blocks during factorization (may increase
stability of factorization.

Notes: Not all options work for all matrix formats
Run with -help to see additional options for particular matrix formats or factorization
algorithms
Notes: Usually this will compute an "exact" solution in one iteration and does
not need a Krylov method (i.e. you can use -ksp_type preonly, or
KSPSetType(ksp,KSPPREONLY) for the Krylov method
