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)
	Direct interpolation. Multi-threaded! (VIENNACL_AMG_INTERPOL_DIRECT).
template<typename InternalType1 , typename InternalType2 >
void	amg_interpol_classic (unsigned int level, InternalType1 &A, InternalType1 &P, InternalType2 &Pointvector, amg_tag &tag)
	Classical interpolation. Don't use with onepass classical coarsening or RS0 (Yang, p.14)! Multi-threaded! (VIENNACL_AMG_INTERPOL_CLASSIC).
template<typename SparseMatrixType >
void	amg_truncate_row (SparseMatrixType &P, unsigned int row, amg_tag &tag)
	Interpolation truncation (for VIENNACL_AMG_INTERPOL_DIRECT and VIENNACL_AMG_INTERPOL_CLASSIC).
template<typename InternalType1 , typename InternalType2 >
void	amg_interpol_ag (unsigned int level, InternalType1 &A, InternalType1 &P, InternalType2 &Pointvector, amg_tag &tag)
	AG (aggregation based) interpolation. Multi-Threaded! (VIENNACL_INTERPOL_SA).
template<typename InternalType1 , typename InternalType2 >
void	amg_interpol_sa (unsigned int level, InternalType1 &A, InternalType1 &P, InternalType2 &Pointvector, amg_tag &tag)
	SA (smoothed aggregate) interpolation. Multi-Threaded! (VIENNACL_INTERPOL_SA).
