amg_pointvector Class Reference

A class for the AMG points. Holds pointers of type amg_point in a vector that can be accessed using [point-index]. Additional list of pointers sorted by influence number and index to improve coarsening performance (see amg_coarse_classic_onepass() in amg_coarse.hpp) Constructs indices for C points on the coarse level, needed for interpolation.

Detailed Description

A class for the AMG points. Holds pointers of type amg_point in a vector that can be accessed using [point-index]. Additional list of pointers sorted by influence number and index to improve coarsening performance (see amg_coarse_classic_onepass() in amg_coarse.hpp) Constructs indices for C points on the coarse level, needed for interpolation.
