hipSPARSE API reference guide
********************************************

The hipSPARSE API reference guide includes an index of the hipSPARSE functions, along with data types
and details of the different hipSPARSE functions by category.

* :ref:`api`
* :ref:`hipsparse-types`
* :ref:`hipsparse_auxiliary_functions` required for subsequent library calls
* :ref:`hipsparse_level1_functions` between a vector in sparse format and a vector in dense format
* :ref:`hipsparse_level2_functions` between a matrix in sparse format and a vector in dense format
* :ref:`hipsparse_level3_functions` between a matrix in sparse format and multiple vectors (matrix) in dense format
* :ref:`hipsparse_extra_functions` for additional linear algebra operations
* :ref:`hipsparse_precond_functions` on a matrix in sparse format to obtain a preconditioner
* :ref:`hipsparse_conversion_functions` to convert a matrix in sparse format to a different storage format
* :ref:`hipsparse_reordering_functions` for reordering sparse matrices
* :ref:`hipsparse_generic_functions` for manipulating sparse matrices
