ZCKGQR

Purpose:

    !>
    !> ZCKGQR tests
    !> ZGGQRF: GQR factorization for N-by-M matrix A and N-by-P matrix B,
    !> ZGGRQF: GRQ factorization for M-by-N matrix A and P-by-N matrix B.
    !>

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(column) dimension M.
    !>

    NP

    !>          NP is INTEGER
    !>          The number of values of P contained in the vector PVAL.
    !>

    PVAL

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

    NN

    !>          NN is INTEGER
    !>          The number of values of N contained in the vector NVAL.
    !>

    NVAL

    !>          NVAL is INTEGER array, dimension (NN)
    !>          The values of the matrix column(row) dimension N.
    !>

    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.
    !>

    NMAX

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