X::ElementType | dot (const X &x, const X &y) const |
Dot product of two vectors. It is assumed that the vectors are consistent on the interior+border partition. | |
template<typename X > | |
Dune::template FieldTraits< typenameX::ElementType >::real_type | norm (const X &x) const |
Norm of a right-hand side vector. The vector must be consistent on the interior+border partition. | |
