Detailed Description

template<typename Number, typename MemorySpace = ::MemorySpace::Host>
struct LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData

A structure whose member variables describe details of the algorithm to be employed by the surrounding class. An object of this type can be used to initialize an object of the surrounding class.

Member Data Documentation

◆ 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

Definition at line 296 of file trilinos_tpetra_solver_direct.h.

◆ symmetric_mode

template<typename Number , typename MemorySpace = ::MemorySpace::Host>
bool LinearAlgebra::TpetraWrappers::SolverDirectKLU2< Number, MemorySpace >::AdditionalData::symmetric_mode

Is A symmetric or not?

Definition at line 301 of file trilinos_tpetra_solver_direct.h.

◆ 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 306 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.

Definition at line 315 of file trilinos_tpetra_solver_direct.h.

◆ 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": ??
