Test Matrices for the Generalized Symmetric Eigenvalue Drivers

Twenty-one different types of test matrices may be generated for generalized symmetric eigenvalue drivers and they are given in Table 10. These test matrices are very similar to the test matrices in Table 9 for testing the symmetric eigenvalue drivers.
