/* >    ZLATMS generates random matrices with specified singular values */
/* >    (or hermitian with specified eigenvalues) */
/* >    for testing LAPACK programs. */
/* > */
/* >    ZLATMS operates by applying the following sequence of */
/* >    operations: */
/* > */
/* >      Set the diagonal to D, where D may be input or */
/* >         computed according to MODE, COND, DMAX, and SYM */
/* >         as described below. */
/* > */
/* >      Generate a matrix with the appropriate band structure, by one */
/* >         of two methods: */
/* > */
/* >      Method A: */
/* >          Generate a dense M x N matrix by multiplying D on the left */
/* >              and the right by random unitary matrices, then: */
/* > */
/* >          Reduce the bandwidth according to KL and KU, using */
/* >              Householder transformations. */
/* > */
/* >      Method B: */
/* >          Convert the bandwidth-0 (i.e., diagonal) matrix to a */
/* >              bandwidth-1 matrix using Givens rotations, "chasing" */
/* >              out-of-band elements back, much as in QR; then convert */
/* >              the bandwidth-1 to a bandwidth-2 matrix, etc.  Note */
/* >              that for reasonably small bandwidths (relative to M and */
/* >              N) this requires less storage, as a dense matrix is not */
/* >              generated.  Also, for hermitian or symmetric matrices, */
/* >              only one triangle is generated. */
/* > */
/* >      Method A is chosen if the bandwidth is a large fraction of the */
/* >          order of the matrix, and LDA is at least M (so a dense */
/* >          matrix can be stored.)  Method B is chosen if the bandwidth */
/* >          is small (< 1/2 N for hermitian or symmetric, < .3 N+M for */
/* >          non-symmetric), or LDA is less than M and not less than the */
/* >          bandwidth. */
/* > */
/* >      Pack the matrix if desired. Options specified by PACK are: */
/* >         no packing */
/* >         zero out upper half (if hermitian) */
/* >         zero out lower half (if hermitian) */
/* >         store the upper half columnwise (if hermitian or upper */
/* >               triangular) */
/* >         store the lower half columnwise (if hermitian or lower */
/* >               triangular) */
/* >         store the lower triangle in banded format (if hermitian or */
/* >               lower triangular) */
/* >         store the upper triangle in banded format (if hermitian or */
/* >               upper triangular) */
/* >         store the entire matrix in banded format */
/* >      If Method B is chosen, and band format is specified, then the */
