DCHKQ3

Purpose:

     DCHKQ3 tests  DGEQP3.

Parameters
    DOTYPE

              DOTYPE is LOGICAL array, dimension (NTYPES)
              The matrix types to be used for testing.  Matrices of type j
              (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
              .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.

    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.

    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 dimension N.

    NNB

              NNB is INTEGER
              The number of values of NB and NX contained in the
              vectors NBVAL and NXVAL.  The blocking parameters are used
              in pairs (NB,NX).

    NBVAL

              NBVAL is INTEGER array, dimension (NNB)
              The values of the blocksize NB.

    NXVAL

              NXVAL is INTEGER array, dimension (NNB)
              The values of the crossover point NX.

    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.

    A

              A is DOUBLE PRECISION array, dimension (MMAX*NMAX)
              where MMAX is the maximum value of M in MVAL and NMAX is the
              maximum value of N in NVAL.

    COPYA

              COPYA is DOUBLE PRECISION array, dimension (MMAX*NMAX)

    S

              S is DOUBLE PRECISION array, dimension
                          (min(MMAX,NMAX))

    TAU

              TAU is DOUBLE PRECISION array, dimension (MMAX)

    WORK

              WORK is DOUBLE PRECISION array, dimension
                          (MMAX*NMAX + 4*NMAX + MMAX)

    IWORK

              IWORK is INTEGER array, dimension (2*NMAX)

    NOUT

              NOUT is INTEGER
              The unit number for output.
