DDRVGBX

Purpose:

     DDRVGB tests the driver routines DGBSV, -SVX, and -SVXX.
     Note that this file is used only when the XBLAS are available,
     otherwise ddrvgb.f defines this subroutine.

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.

    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.

    NRHS

              NRHS is INTEGER
              The number of right hand side vectors to be generated for
              each linear system.

    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.

    TSTERR

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

    A

              A is DOUBLE PRECISION array, dimension (LA)

    LA

              LA is INTEGER
              The length of the array A.  LA >= (2*NMAX-1)*NMAX
              where NMAX is the largest entry in NVAL.

    AFB

              AFB is DOUBLE PRECISION array, dimension (LAFB)

    LAFB

              LAFB is INTEGER
              The length of the array AFB.  LAFB >= (3*NMAX-2)*NMAX
              where NMAX is the largest entry in NVAL.

    ASAV

              ASAV is DOUBLE PRECISION array, dimension (LA)

    B

              B is DOUBLE PRECISION array, dimension (NMAX*NRHS)

    BSAV

              BSAV is DOUBLE PRECISION array, dimension (NMAX*NRHS)

    X

              X is DOUBLE PRECISION array, dimension (NMAX*NRHS)

    XACT

              XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS)

    S

              S is DOUBLE PRECISION array, dimension (2*NMAX)

    WORK

              WORK is DOUBLE PRECISION array, dimension
                          (NMAX*max(3,NRHS,NMAX))

    RWORK

              RWORK is DOUBLE PRECISION array, dimension
                          (max(2*NMAX,NMAX+2*NRHS))

    IWORK

              IWORK is INTEGER array, dimension (2*NMAX)

    NOUT

              NOUT is INTEGER
              The unit number for output.
