SCKGSV

Purpose:

    !>
    !> SCKGSV tests SGGSVD:
    !>        the GSVD 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 dimension M.
    !>

    PVAL

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

    NVAL

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

    A

    !>          A is REAL array, dimension (NMAX*NMAX)
    !>

    AF

    !>          AF is REAL array, dimension (NMAX*NMAX)
    !>

    B

    !>          B is REAL array, dimension (NMAX*NMAX)
    !>

    BF

    !>          BF is REAL array, dimension (NMAX*NMAX)
    !>

    !>          U is REAL array, dimension (NMAX*NMAX)
    !>

    V

    !>          V is REAL array, dimension (NMAX*NMAX)
    !>

    Q

    !>          Q is REAL array, dimension (NMAX*NMAX)
    !>

    ALPHA

    !>          ALPHA is REAL array, dimension (NMAX)
    !>

    BETA

    !>          BETA is REAL array, dimension (NMAX)
    !>

    R

    !>          R is REAL array, dimension (NMAX*NMAX)
    !>

    IWORK

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

    !>          WORK is REAL array, dimension (NMAX*NMAX)
    !>

    RWORK

    !>          RWORK is REAL array, dimension (NMAX)
    !>

    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 SLATMS returns an error code, the absolute value
    !>                 of it is returned.
