+linear eigenvalue problems formulated in either standard or generalized form,
+as well as other related problems such as the singular value decomposition.
+The emphasis of the software is on methods and techniques appropriate for
+problems in which the associated matrices are sparse, for example, those
+arising after the discretization of partial differential equations.")
