Namespaces | |
namespace | viennacl |
Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them. | |
namespace | viennacl::linalg |
Provides all linear algebra operations which are not covered by operator overloads. | |
namespace | viennacl::linalg::detail |
Namespace holding implementation details for linear algebra routines. Usually not of interest for a library user. | |
namespace | viennacl::linalg::detail::amg |
Implementation namespace for algebraic multigrid preconditioner. | |
Functions | |
template<typename InternalType1 , typename InternalType2 > | |
void | amg_interpol (unsigned int level, InternalType1 &A, InternalType1 &P, InternalType2 &Pointvector, amg_tag &tag) |
