transpose_mode

template<typename Number , typename MemorySpace = ::MemorySpace::Host>

std::string LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData::transpose_mode

Decide which system to solve "NOTRANS": Ax=b (default) "TRANS": A^Tx=b "CONJ": A^*x=b

symmetric_mode

template<typename Number , typename MemorySpace = ::MemorySpace::Host>

bool LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData::symmetric_mode

Is A symmetric or not?

equilibrate_matrix

template<typename Number , typename MemorySpace = ::MemorySpace::Host>

bool LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData::equilibrate_matrix

Equilibrate matrix before solving? (default: true)

Definition at line 280 of file trilinos_tpetra_solver_direct.h.

column_permutation

template<typename Number , typename MemorySpace = ::MemorySpace::Host>

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.

iterative_refinement

template<typename Number , typename MemorySpace = ::MemorySpace::Host>

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": ??
