Detailed Description

Fabric class for CGUzawa. Caution: As the class CGUzawa requires the submatrices for constructing a solver and not the full matrix, the fabric returns a solver for the system specified at construction time, not for the system specified when asking for a solver. This Trojan Horse behaviour is a workaround.

◆ info()

virtual std::ostream & vectorial::CGUzawaFabric::info ( std::ostream & os ) const

inlineprotectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

◆ operator()() [1/2]

virtual Operator< Real > * concepts::SolverFabric< Real >::operator() ( )

pure virtualinherited

Creates a linear solver from matrix. The caller is responsible for the deletion of the delivered object.

Returns: Reference to the linear solver

Implemented in concepts::UmfpackFabric.
