| viennacl::linalg
| Provides all linear algebra operations which are not covered by operator overloads.
| viennacl::linalg::host_based
| Holds all compute kernels with conventional host-based execution (buffers in CPU RAM).
| viennacl::linalg::host_based::detail
| Helper functions for the host-based linear algebra backend.
