Intrinsic application method without argument

Implemented in concepts::ShiftAndInvertOperatorForGEVPs< F >, concepts::LapackChol, concepts::Mumps< F >, concepts::MumpsOverlap< F >, concepts::Newton< F >, and concepts::SolverConjugate.

◆ apply_() [2/2]

template<class F >

virtual void concepts::VecOperator< F >::apply_	(	const Vector< F > &	fncY,
		Vector< F > &	fncX

Intrinsic application method, i.e. real Operator and real Vector or complex Operator and real Vector.

Implemented in concepts::SolverConjugate, concepts::ShiftAndInvertOperatorForGEVPs< F >, concepts::Mumps< F >, concepts::MumpsOverlap< F >, and concepts::LapackChol.

◆ dimX()

template<class F >

virtual const uint concepts::Operator< F >::dimX ( ) const

Returns the size of the image space of the operator (number of rows of the corresponding matrix)

Examples: hpFEM2d-simple.cc, hpFEM2d.cc, and matfileTutorial.cc.

Definition at line 93 of file compositions.hh.

◆ dimY()

Returns the size of the source space of the operator (number of columns of the corresponding matrix)

Examples: matfileTutorial.cc.

Returns information in an output stream.

Reimplemented from concepts::Operator< F >.

◆ operator()() [1/5]

template<class F >

void concepts::VecOperator< F >::operator() ( )

virtual

Application method without second argument. Used for parallel solvers.

Reimplemented from concepts::Operator< F >.

◆ operator()() [2/5]

template<class F >

virtual void concepts::VecOperator< F >::operator()	(	const Function< c_type > &	fncY,
		Function< c_type > &	fncX
	)

virtual

Application operator for complex function fncY.

Computes fncX = A(fncY) where A is this operator. fncX becomes complex.

In derived classes its enough to implement the operator() for complex Operator's. If a real counterpart is not implemented, the function fncY is splitted into real and imaginary part and the application operator for real functions is called for each. Then the result is combined.

If in a derived class the operator() for complex Operator's is not implemented, a exception is thrown from here.

Reimplemented from concepts::Operator< F >.

Computes fncX = A(fncY) where A is this operator.

fncX becomes the type of the operator, for real data it becomes real, for complex data it becomes complex.

In derived classes its enough to implement the operator() for real Operator's. If a complex counterpart is not implemented, the function fncY is transformed to a complex function and then the application operator for complex functions is called.
