If I understand correctly, I should do something like this:
std::vector<std::unique_ptr<Multigrid<LevelVectorType > > >
multigrids_sc_pointers(triangulation.n_global_levels());
for (unsigned int level = 0; level<triangulation.n_global_levels();
++level)
multigrids_sc_pointers[level] = new Multigrid<LevelVectorType >(
mg_matrix_sc,
mg_coarse_sc,
mg_transfer_sc,
mg_smoother_sc,
mg_smoother_sc);
It does not work, I have almost no experience with unique pointers and I
have no idea how to do it. Could you help me?
Thanks
