Detailed Description

template<class F>
class vectorial::BlockOperator< F >

Operator defined by 4 operators arranged in 2x2 blocks:

\[ \left(\begin{array}{lr}A&B\\C&D\end{array}\right) \]

. BlockOperator is an Operator on a vectorial::Space of vectorial dimension 2, consisting of, say, spc1 and spc2. A is an operator spc1->spc1, B is spc2->spc1, C is spc1->spc2 and D is spc2->spc2. This is useful for example in mixed FEM for the Stokes problem, where spc1 is the space of velocities and spc2 is the space of pressures. spc1 is then again a vectorial::Space.

Member Function Documentation

◆ dimX()

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

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()

template<class F >
virtual const uint concepts::Operator< F >::dimY ( ) const
inlinevirtualinherited

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

Examples
matfileTutorial.cc.

Definition at line 98 of file compositions.hh.

◆ info()

template<class F >
virtual std::ostream & vectorial::BlockOperator< F >::info ( std::ostream &  os) const
protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::Operator< F >.

◆ operator()() [1/3]

template<class F >
virtual void concepts::Operator< F >::operator() ( )
virtualinherited

◆ operator()() [2/3]

template<class F >
virtual void vectorial::BlockOperator< F >::operator() ( const concepts::Function< F > &  fncY,
concepts::Function< F > &  fncX 
)
virtual

Application operator for functions.

Reimplemented from concepts::Operator< F >.

◆ operator()() [3/3]

template<class F >
virtual void concepts::Operator< F >::operator() ( const Function< c_type > &  fncY,
Function< c_type > &  fncX 
)
virtualinherited

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.
