## 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.

## Functions

void | viennacl::linalg::detail::spai::make_rotation_matrix (MatrixT &mat, vcl_size_t new_size, vcl_size_t off_diagonal_distance=4)
template<typename MatrixT >
double | viennacl::linalg::detail::spai::determinant (boost::numeric::ublas::matrix_expression< MatrixT > const &mat_r)
