virtual field_type | dot (const X &x, const X &y) const override |
Dot product of two vectors. It is assumed that the vectors are consistent on the interior+border partition. | |
virtual real_type | norm (const X &x) const override |
Norm of a right-hand side vector. The vector must be consistent on the interior+border partition. | |
virtual SolverCategory::Category | category () const override |
Category of the scalar product (see SolverCategory::Category) | |
Scalar product for overlapping Schwarz methods.
Consistent vectors in interior and border are assumed.
X | The type of the sequential vector to use for the left hand side, e.g. BlockVector or another type fulfilling the ISTL vector interface. |
C | The type of the communication object. This must either be OwnerOverlapCopyCommunication or a type implementing the same interface. |
typedef C Dune::ParallelScalarProduct< X, C >::communication_type |
The type of the communication object.
This must either be OwnerOverlapCopyCommunication or a type implementing the same interface.
typedef X Dune::ParallelScalarProduct< X, C >::domain_type |
The type of the vector to compute the scalar product on.
E.g. BlockVector or another type fulfilling the ISTL vector interface.
typedef X::field_type Dune::ParallelScalarProduct< X, C >::field_type |
The field type used by the vector type domain_type.
typedef FieldTraits<field_type>::real_type Dune::ParallelScalarProduct< X, C >::real_type |
