Detailed Description
template<class M, class X, class Y>
class Dune::AssembledLinearOperator< M, X, Y >
class Dune::AssembledLinearOperator< M, X, Y >
A linear operator exporting itself in matrix form.
Linear Operator that exports the operator in matrix form. This is needed for certain solvers, such as LU decomposition, ILU preconditioners or BiCG-Stab (because of multiplication with A^T).
