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)
 Calls the right function to build interpolation matrix.
template<typename InternalType1 , typename InternalType2 >
void amg_interpol_direct (unsigned int level, InternalType1 &A, InternalType1 &P, InternalType2 &Pointvector, amg_tag &tag)
