CDRVLS

Purpose:

     CDRVLS tests the least squares driver routines CGELS, CGELST,
     CGETSLS, CGELSS, CGELSY
     and CGELSD.

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.
              The matrix of type j is generated as follows:
              j=1: A = U*D*V where U and V are random unitary matrices
                   and D has random entries (> 0.1) taken from a uniform
                   distribution (0,1). A is full rank.
              j=2: The same of 1, but A is scaled up.
              j=3: The same of 1, but A is scaled down.
              j=4: A = U*D*V where U and V are random unitary matrices
                   and D has 3*min(M,N)/4 random entries (> 0.1) taken
                   from a uniform distribution (0,1) and the remaining
                   entries set to 0. A is rank-deficient.
              j=5: The same of 4, but A is scaled up.
              j=6: The same of 5, but A is scaled down.

    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)

    NNB

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

              The values of the blocksize NB.

    NXVAL

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

    NNS

              NNS is INTEGER
              The number of values of NRHS contained in the vector NSVAL.

    NSVAL

    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.

    TSTERR

              TSTERR is LOGICAL
              Flag that indicates whether error exits are to be tested.

    A

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

              COPYS is REAL array, dimension
                          (min(MMAX,NMAX))
