Classes
class	viennacl::linalg::amg_coarse_problem_too_large_exception
class	viennacl::linalg::amg_precond< MatrixT >
	AMG preconditioner class, can be supplied to solve()-routines. More...
class	viennacl::linalg::amg_precond< compressed_matrix< NumericT, AlignmentV > >

Namespaces
	viennacl
	Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.
	viennacl::linalg
	Provides all linear algebra operations which are not covered by operator overloads.
	viennacl::linalg::detail
	Namespace holding implementation details for linear algebra routines. Usually not of interest for a library user.
