Simple drivers are provided to compute all the eigenvalues and (optionally) the eigenvectors of the following types of problems:

where `A` and `B` are symmetric or Hermitian and `B` is positive definite.
For all these problems the eigenvalues are real. The matrices `Z`
of computed eigenvectors satisfy
(problem types 1 and 3) or
(problem type 2), where is a diagonal matrix with the eigenvalues
on the diagonal. `Z` also satisfies
(problem types 1 and 2) or (problem type 3).

The routines are listed in Table 2.6.
