Class template `Dune::GDT::MatrixOperator`¶

template<class AGV, size_t s_r, size_t s_rC, size_t r_r, size_t r_rC, class F, class M, class SGV, class RGV> class Dune::GDT::MatrixOperator¶

Base class for linear operators which are assembled into a matrix.

We derive from the XT::Grid::ElementAndIntersectionFunctor and povide custom append() methods to allow to add local element and intersection operators. We also hold the target matrix into which we want to assemble. The operator is assembled by walking over the given assembly_grid_view. If you want to assemble an operator only on a smaller grid view, consider to append this operator to another walker or provide appropriate filters.

Note

See ConstMatrixOperator and OperatorInterface for a description of the template arguments.

Note

In compute_locally, the filters are evaluated w.r.t. assembly_grid_view and not the grid view of the walker this operator is appended to. This might not be what we want.

template<> Dune::GDT::MatrixOperator::MatrixOperator<AGV, s_r, s_rC, r_r, r_rC, F, M, SGV, RGV>(ThisType &other)¶: Note

Performs something like a shallow copy (as required by ElementAndIntersectionFunctor), i.e. the copied operator shares the matrix.

Note

Manual copy required to duplicate the local assemblers
