Detailed Description

template<class local_matrix_type, class local_graph_type, bool lumping>
class MueLu::MatrixConstruction::PointwiseFillReuseFunctor< local_matrix_type, local_graph_type, lumping >

Functor that fills the filtered matrix while reusing the graph of the matrix before dropping, blockSize == 1.

The dropped graph is built from scratch. The filtered matrix reuses the graph of the matrix before dropping. Lumps dropped entries to the diagonal if lumping==true.
