## Classes

class | viennacl::linalg::detail::FastMatrix< SCALARTYPE >
| Internal helper class representing a row-major dense matrix used for the QR method for the purpose of computing eigenvalues. 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.
