Generalized Symmetric Definite Eigenvalue Problems: LAPACK Driver Routines

This
topic
describes LAPACK driver routines used for solving generalized symmetric definite eigenproblems. See also computational routines that can be called to solve these problems. Table
"Driver Routines for Solving Generalized Symmetric Definite 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.

Routine Name
Operation performed
Computes all eigenvalues and, optionally, eigenvectors of a real / complex generalized symmetric /Hermitian positive-definite eigenproblem.
Computes all eigenvalues and, optionally, eigenvectors of a real / complex generalized symmetric /Hermitian positive-definite eigenproblem. If eigenvectors are desired, it uses a divide and conquer method.
Computes selected eigenvalues and, optionally, eigenvectors of a real / complex generalized symmetric /Hermitian positive-definite eigenproblem.
Computes all eigenvalues and, optionally, eigenvectors of a real / complex generalized symmetric /Hermitian positive-definite eigenproblem with matrices in packed storage.
