## Classes
class | viennacl::linalg::detail::spai::fspai_tag
| A tag for FSPAI. Experimental. More...

## 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.
| viennacl::linalg::detail::spai
| Implementation namespace for sparse approximate inverse preconditioner.
