Detailed Description
template<class X, class C>
class Dune::ParallelScalarProduct< X, C >
class Dune::ParallelScalarProduct< X, C >
Scalar product for overlapping Schwarz methods.
Consistent vectors in interior and border are assumed.
- Template Parameters
-
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.
