ZCKCSD

Purpose:

    !>
    !> ZCKCSD tests ZUNCSD:
    !>        the CSD for an M-by-M unitary matrix X partitioned as
    !>        [ X11 X12; X21 X22 ]. X11 is P-by-Q.
    !>

Parameters
    NM

    !>          NM is INTEGER
    !>          The number of values of M contained in the vector MVAL.
    !>

    MVAL

    !>          MVAL is INTEGER array, dimension (NM)
    !>          The values of the matrix row dimension M.
    !>

    PVAL

    !>          PVAL is INTEGER array, dimension (NM)
    !>          The values of the matrix row dimension P.
    !>

    QVAL

    !>          QVAL is INTEGER array, dimension (NM)
    !>          The values of the matrix column dimension Q.
    !>

    NMATS

    !>          NMATS is INTEGER
    !>          The number of matrix types to be tested for each combination
    !>          of matrix dimensions.  If NMATS >= NTYPES (the maximum
    !>          number of matrix types), then all the different types are
    !>          generated for testing.  If NMATS < NTYPES, another input line
    !>          is read to get the numbers of the matrix types to be used.
    !>

    ISEED

    !>          ISEED is INTEGER array, dimension (4)
    !>          On entry, the seed of the random number generator.  The array
    !>          elements should be between 0 and 4095, otherwise they will be
    !>          reduced mod 4096, and ISEED(4) must be odd.
    !>          On exit, the next seed in the random number sequence after
    !>          all the test matrices have been generated.
    !>

    THRESH

    !>          THRESH is DOUBLE PRECISION
    !>          The threshold value for the test ratios.  A result is
    !>          included in the output file if RESULT >= THRESH.  To have
    !>          every test ratio printed, use THRESH = 0.
    !>

    MMAX

    !>          MMAX is INTEGER
    !>          The maximum value permitted for M, used in dimensioning the
    !>          work arrays.
    !>

    X

    !>          X is COMPLEX*16 array, dimension (MMAX*MMAX)
    !>

    XF

    !>          XF is COMPLEX*16 array, dimension (MMAX*MMAX)
    !>

    U1

    !>          U1 is COMPLEX*16 array, dimension (MMAX*MMAX)
    !>

    U2

    !>          U2 is COMPLEX*16 array, dimension (MMAX*MMAX)
    !>

    V1T

    !>          V1T is COMPLEX*16 array, dimension (MMAX*MMAX)
    !>

    V2T

    !>          V2T is COMPLEX*16 array, dimension (MMAX*MMAX)
    !>

    THETA

    !>          THETA is DOUBLE PRECISION array, dimension (MMAX)
    !>

    IWORK

    !>          IWORK is INTEGER array, dimension (MMAX)
    !>

    WORK

    !>          WORK is COMPLEX*16 array
    !>

    RWORK

    !>          RWORK is DOUBLE PRECISION array
    !>

    NIN

    !>          NIN is INTEGER
    !>          The unit number for input.
    !>

    NOUT

    !>          NOUT is INTEGER
    !>          The unit number for output.
    !>

    INFO

    !>          INFO is INTEGER
    !>          = 0 :  successful exit
    !>          > 0 :  If ZLAROR returns an error code, the absolute value
    !>                 of it is returned.
