Detailed Description

template<class local_matrix_type, bool useGreedyDirichlet>
class MueLu::BoundaryDetection::VectorDirichletFunctor< local_matrix_type, useGreedyDirichlet >

Functor for marking nodes as Dirichlet in a block operator.

Assumes a single fixed block size specified by blockSize. Marks blocks as Dirichlet when one row is Dirichlet (useGreedyDirichlet==true) or when all rows are Dirichlet (useGreedyDirichlet==false). A row is marked as Dirichlet boundary if fewer than dirichletNonzeroThreshold entries are larger in absolute value than dirichletThreshold. It is assumed that boundaryNodes was initialized to false.
