Detailed Description

template<class local_matrix_type>
class MueLu::BoundaryDetection::RowSumFunctor< local_matrix_type >

Functor for marking nodes as Dirichlet based on rowsum.

A row is marked as Dirichlet boundary if the sum of off-diagonal values is smaller in absolute value than the diagonal multiplied by the threshold rowSumTol. It is assumed that boundaryNodes was initialized to false.
