Detailed Description
template<typename M>
class Dune::SuperLU< M >
class Dune::SuperLU< M >
SuperLu Solver.
Uses the well known SuperLU package to solve the system.
SuperLU supports single and double precision floating point and complex numbers. Unfortunately these cannot be used at the same time. Therefore users must set SUPERLU_NTYPE (0: float, 1: double, 2: std::complex<float>, 3: std::complex<double>) if the numeric type should be different from double.
Constructor & Destructor Documentation
◆ SuperLU()
template<typename M >
|
inline |
Constructs the SuperLU solver.
- Parameters
-
matrix The matrix of the system to solve. config ParameterTree containing solver parameters.
ParameterTree Key | Meaning |
---|---|
verbose | The verbosity level. default=false |
reuseVector | Reuse initially allocated vectors in apply. default=true |
Member Function Documentation
◆ apply()
template<typename M >
|
inline |
apply inverse operator, with given convergence criteria.
- Warning
- Right hand side b may be overwritten!
- Parameters
-
x The left hand side to store the result in. b The right hand side reduction The minimum defect reduction to achieve. res Object to store the statistics about applying the operator.
- Exceptions
-
SolverAbort When the solver detects a problem and cannot continue
