*********************************
Dense matrix LAPACK functions
*********************************

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

* :ref:`dense_triangular`: Based on Gaussian elimination.
* :ref:`dense_orthogonal`: Based on Householder reflections.
* :ref:`dense_reductions`: Transformation of matrices and problems into equivalent forms.
* :ref:`dense_linears`: Based on triangular factorizations.
* :ref:`dense_leastsqr`: Based on orthogonal factorizations.
* :ref:`dense_eigens`: Eigenproblems for general and symmetric matrices.
* :ref:`dense_svds`: Singular values and related problems for general matrices.
