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.
