◆ CouplingOperator()

template<int dim, typename number, int n_components>

CouplingOperator< dim, number, n_components >::CouplingOperator	(	const Inclusions< dim > &	inclusions,
		const DoFHandler< dim > &	dof_handler,
		const AffineConstraints< number > &	constraints = AffineConstraints<number>(),
		const MappingQ< dim > &	mapping = MappingQ1<dim>(),
		const FiniteElement< dim > &	fe = FE_Q<dim>(1) )

Constructor. Takes an Inclusions instance, a reference to the background triangulation and an optional mapping to initialize the evaluator on remote points.
