Generalized Nonsymmetric Eigenproblems

This topic describes LAPACK driver routines used for solving generalized nonsymmetric eigenproblems. See also computational routines that can be called to solve these problems. Table "Driver Routines for Solving Generalized Nonsymmetric Eigenproblems" lists all such driver routines for the FORTRAN 77 interface. The corresponding routine names in the Fortran 95 interface are without the first symbol.
