用代数多重网格法求解大型稀疏线性系统的c++库 ddemidov/amgcl 源码

AMGCL AMGCL is a header-only C++ library for solving large sparse linear systems with algebraic multigrid (AMG) method. AMG is one of the most effective iterative methods for solution of equation systems arising, for example, from discretizing PDEs on unstructured grids. The method can be used as a
