Detailed Description

template<class local_matrix_type, bool lumping>
class MueLu::MatrixConstruction::PointwiseFillNoReuseFunctor< local_matrix_type, lumping >

Functor does not reuse the graph of the matrix for a problem with blockSize == 1.

The dropped graph and the filtered matrix are built from scratch. Lumps dropped entries to the diagonal if lumping==true.
