Amesos_Taucs (const Epetra_LinearProblem &LinearProblem) | |
Default constructor. | |
~Amesos_Taucs (void) | |
Default destructor. | |
int | SymbolicFactorization () |
Performs SymbolicFactorization on the matrix A. | |
int | NumericFactorization () |
Performs NumericFactorization on the matrix A. | |
int | Solve () |
Solves A X = B (or AT x = B). | |
const Epetra_LinearProblem * | GetProblem () const |
Returns the Epetra_LinearProblem. | |
bool | MatrixShapeOK () const |
Returns true if the solver can handle this matrix shape. | |

Amesos_Taucs::Amesos_Taucs | ( | const Epetra_LinearProblem & | LinearProblem | ) |
Default constructor.
Amesos_Taucs::~Amesos_Taucs | ( | void | ) |
Default destructor.
const Epetra_Comm& Amesos_Taucs::Comm | ( | ) | const [inline, virtual] |
Returns a pointer to the Epetra_Comm communicator associated with this operator.
Implements Amesos_BaseSolver.
const Epetra_LinearProblem* Amesos_Taucs::GetProblem | ( | ) | const [inline, virtual] |
Returns the Epetra_LinearProblem.
Warning! Do not call return->SetOperator(...)
to attempt to change the Epetra_Operator
object (even if the new matrix has the same structure). This new operator matrix will be ignored!
Implements Amesos_BaseSolver.
void Amesos_Taucs::GetTiming | ( | Teuchos::ParameterList & | TimingParameterList | ) | const [inline, virtual] |
Extracts timing information from the current solver and places it in the parameter list.
Reimplemented from Amesos_BaseSolver.
bool Amesos_Taucs::MatrixShapeOK | ( | ) | const [virtual] |
Returns true if the solver can handle this matrix shape.
Returns true if the matrix shape is one that the underlying sparse direct solver can handle. Classes that work only on square matrices should return false for rectangular matrices. Classes that work only on symmetric matrices whould return false for non-symmetric matrices.
Implements Amesos_BaseSolver.
int Amesos_Taucs::NumericFactorization | ( | ) | [virtual] |
Performs NumericFactorization on the matrix A.
In addition to performing numeric factorization on the matrix A, the call to NumericFactorization() implies that no change will be made to the underlying matrix without a subsequent call to NumericFactorization().

int Amesos_Taucs::NumNumericFact | ( | ) | const [inline, virtual] |
Returns the number of numeric factorizations performed by this object.
