The Generalized Symmetric Eigenvalue Drivers

The driver routines for the generalized symmetric eigenvalue problem are

xSYGV/xHEGV

eigenvalue/vector driver for symmetric matrices A and B,

xSYGVD/xHEGVD

divide and conquer eigenvalue/vector driver for symmetric matrices A and B,

xSYGVX/xHEGVX

selected eigenvalue/vector driver for symmetric matrices A and B,

xSPGV/xHPGV

eigenvalue/vector driver for symmetric packed matrices A and B,

xSPGVD/xHPGVD

divide and conquer eigenvalue/vector driver for symmetric packed matrices A and B,

xSPGVX/xHPGVX

selected eigenvalue/vector driver for symmetric packed matrices A and B,

xSBGV/xHBGV

eigenvalue/vector driver for symmetric and banded matrices A and B,

xSBGVD/xHBGVD

divide and conquer eigenvalue/vector driver for symmetric and banded matrices A and B,

xSBGVX/xHBGVX

selected eigenvalue/vector driver for symmetric and banded matrices A and B.

In all these drivers, B is assumed to be positive definite.
