SCKGQR

Purpose:

     SCKGQR tests
     SGGQRF: GQR factorization for N-by-M matrix A and N-by-P matrix B,
     SGGRQF: 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 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)

    AQ

              AQ is REAL array, dimension (NMAX*NMAX)

    AR

              AR is REAL array, dimension (NMAX*NMAX)

    TAUA

              TAUA is REAL array, dimension (NMAX)

    B

              B is REAL array, dimension (NMAX*NMAX)

    BF

              BF is REAL array, dimension (NMAX*NMAX)

    BZ

              BZ is REAL array, dimension (NMAX*NMAX)

    BT

              BT is REAL array, dimension (NMAX*NMAX)

    BWK

              BWK is REAL array, dimension (NMAX*NMAX)

    TAUB

              TAUB is REAL array, dimension (NMAX)

    WORK

              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.
