Detailed Description
template<typename F>
class concepts::DiagonalSolver< F >
A solver for diagonal matrices.

Reimplemented from concepts::Operator< F >.
◆ operator()() [1/6]

Application operator without argument.
Reimplemented in concepts::VecOperator< F >, concepts::VecOperator< T >, concepts::VecOperator< F::d_type >, concepts::VecOperator< Cmplx >, concepts::VecOperator< Real >, and concepts::BelosSolver< T >.
◆ operator()() [2/6]
|
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 >.

◆ operator()() [3/6]

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.
Reimplemented in concepts::VecOperator< T >, concepts::VecOperator< Real >, concepts::LiCo< F >, concepts::LiCoI< F >, concepts::Multiple< F >, concepts::VecOperator< F >, concepts::VecOperator< F::d_type >, and concepts::VecOperator< Cmplx >.
