Member Function Documentation

dimX()

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

inlinevirtualinherited

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

Definition at line 93 of file compositions.hh.

dimY()

virtual const uint concepts::Operator< Real >::dimY ( ) const

inlinevirtualinherited

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

Definition at line 98 of file compositions.hh.

info()

virtual std::ostream & concepts::Constrained::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::Operator< Real >.

operator()() [1/3]

virtual void concepts::Operator< Real >::operator() ( )

virtualinherited

Application operator without argument

operator()() [2/3]

virtual void concepts::Operator< Real >::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.

operator()() [3/3]

virtual void concepts::Operator< Real >::operator() ( const Function< r_type > &  fncY, Function< Real > &  fncX  )

virtualinherited

Application operator for real function fncY.

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.

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