Detailed Description
template<class Op>
class Kaskade::DirectPreconditioner< Op >
class Kaskade::DirectPreconditioner< Op >
A direct preconditioner applicable to assembled operators.
- Template Parameters
-
Op the assembled operator. Note that Op::matrix_type must be MatrixAsTriplet<> and Op::Domain must be LinearProductSpace<>. This is satisfied for assembled Galerkin operators coming from a VariationalFunctionalAssembler.
