**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,
