## 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.

## Functions
template<typename NumericT >
void | viennacl::linalg::detail::precondition (viennacl::compressed_matrix< NumericT > const &A, viennacl::compressed_matrix< NumericT > &L, viennacl::vector< NumericT > &diag_L, viennacl::compressed_matrix< NumericT > &L_trans, chow_patel_tag const &tag)
