## 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::opencl
| Holds all routines providing OpenCL linear algebra operations.
| viennacl::linalg::opencl::amg
