ZDRVGB

Purpose:
 ZDRVGB tests the driver routines ZGBSV and -SVX.
Parameters
[in]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.
[in]NN
          NN is INTEGER
          The number of values of N contained in the vector NVAL.
[in]NVAL
          NVAL is INTEGER array, dimension (NN)
          The values of the matrix column dimension N.
[in]NRHS
          NRHS is INTEGER
          The number of right hand side vectors to be generated for
          each linear system.
[in]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.
[in]TSTERR
          TSTERR is LOGICAL
          Flag that indicates whether error exits are to be tested.
[out]A
          A is COMPLEX*16 array, dimension (LA)
[in]LA
          LA is INTEGER
          The length of the array A.  LA >= (2*NMAX-1)*NMAX
          where NMAX is the largest entry in NVAL.
[out]AFB
          AFB is COMPLEX*16 array, dimension (LAFB)
[in]LAFB
          LAFB is INTEGER
          The length of the array AFB.  LAFB >= (3*NMAX-2)*NMAX
          where NMAX is the largest entry in NVAL.
[out]ASAV
          ASAV is COMPLEX*16 array, dimension (LA)
[out]B
          B is COMPLEX*16 array, dimension (NMAX*NRHS)
[out]BSAV
          BSAV is COMPLEX*16 array, dimension (NMAX*NRHS)
[out]X
          X is COMPLEX*16 array, dimension (NMAX*NRHS)
[out]XACT
          XACT is COMPLEX*16 array, dimension (NMAX*NRHS)
[out]S
          S is DOUBLE PRECISION array, dimension (2*NMAX)
[out]WORK
          WORK is COMPLEX*16 array, dimension
                      (NMAX*max(3,NRHS,NMAX))
[out]RWORK
          RWORK is DOUBLE PRECISION array, dimension
                      (max(NMAX,2*NRHS))
[out]IWORK
          IWORK is INTEGER array, dimension (NMAX)
[in]NOUT
          NOUT is INTEGER
          The unit number for output.
