***************************
hipSOLVER LAPACK functions
***************************

LAPACK routines solve complex numerical linear algebra problems. These functions are organized
into the following categories:

*  :ref:`triangular`: Based on Gaussian elimination.
*  :ref:`orthogonal`: Based on Householder reflections.
*  :ref:`reductions`: Transformation of matrices and problems into equivalent forms.
*  :ref:`linears`: Based on triangular factorizations.
*  :ref:`leastsqr`: Based on orthogonal factorizations.
*  :ref:`eigens`: Eigenproblems for symmetric matrices.
*  :ref:`svds`: Singular values and related problems for general matrices.
