Eighteen different types of test matrices may be generated for
the symmetric eigenvalue drivers. The first 15 test matrices are the
same as the types of matrices used to test the symmetric eigenvalue
computational routines, and are given in Table 8.
Table 9 shows the types available,
along with the numbers used to refer to the matrix types.
Except as noted, all matrices have 124#124 entries.
The expression 281#281 means a real diagonal matrix 282#282
with 124#124 entries conjugated
by a unitary (or real orthogonal) matrix 132#132.
The eigenvalue distributions have the same meanings as in the
nonsymmetric case (see Section 5.2.1).
