| 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::detail
| Helper functions for OpenCL-accelerated linear algebra operations.
