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.
