◆ Matrix

template<typename Backend , typename VU , typename VV , typename E >
using Dune::PDELab::Backend::Matrix = typedef typename impl::BackendMatrixSelector<Backend, VU, VV, E>::Type

alias of the return type of BackendMatrixSelector

This alias can be used as a short hand for retrieving the matrix type for given matrix backend, domain, range and field type.

typedef typename Dune::PDELab::BackendMatrixSelector<Backend,VU,VV,E>::Type Mat;

simplifies to

or

◆ Native

template<typename T >
using Dune::PDELab::Backend::Native = typedef typename native_type<T>::type

Alias of the native container type associated with T or T itself if it is not a backend wrapper.

◆ Vector

template<typename GridFunctionSpace , typename FieldType >
using Dune::PDELab::Backend::Vector = typedef typename impl::BackendVectorSelector<GridFunctionSpace, FieldType>::Type

alias of the return type of BackendVectorSelector

This alias can be used as a short hand for retrieving the vector type for a grid function space and a given field type. The typedef

typedef typename Dune::PDELab::BackendVectorSelector<GFS,FT>::Type Vec;

simplifies to

or
