Detailed Description

template<typename 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 >

Dune::SuperLU< M >::SuperLU ( const Matrix &  mat, const ParameterTree &  config  )

inline

Constructs the SuperLU solver.

Parameters

mat	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 >

void Dune::SuperLU< M >::apply ( domain_type &  x, range_type &  b, double  reduction, InverseOperatorResult &  res  )

inlineoverride

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
