bool LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData::symmetric_mode |
Is A symmetric or not?

std::string LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData::column_permutation |
Choose an ordering strategy "COLAMD": approximate minimum degree column ordering (default). "NATURAL": natural ordering. "MMD_ATA": minimum degree ordering on the structure of A^TA. "MMD_AT_PLUS_A": minimum degree ordering on the structure of A^T+A.

std::string LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData::iterative_refinement |
Perform iterative refinement? "NO": no (default) "SINGLE": yes, use single precision for the residual "DOUBLE": yes, use double precision for the residual "EXTRA": ??
