virtual field_type dot (const X &x, const X &y)=0
 Dot product of two vectors. It is assumed that the vectors are consistent on the interior+border partition.
 
virtual double norm (const X &x)=0
 Norm of a right-hand side vector. The vector must be consistent on the interior+border partition.

Detailed Description

template<class X>
class Dune::ScalarProduct< X >

Base class for scalar product and norm computation.

Krylov space methods need to compute scalar products and norms (for convergence test only). These methods have to know about the underlying data decomposition. For the sequential case a default implementation is provided.
