Purpose:



 ZDRVGB tests the driver routines ZGBSV and -SVX.

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 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 is COMPLEX*16 array, dimension (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 COMPLEX*16 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 COMPLEX*16 array, dimension (LA)



          B is COMPLEX*16 array, dimension (NMAX*NRHS)

BSAV



          BSAV is COMPLEX*16 array, dimension (NMAX*NRHS)



          X is COMPLEX*16 array, dimension (NMAX*NRHS)

XACT



          XACT is COMPLEX*16 array, dimension (NMAX*NRHS)



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

WORK



          WORK is COMPLEX*16 array, dimension


                      (NMAX*max(3,NRHS,NMAX))

RWORK



          RWORK is DOUBLE PRECISION array, dimension


                      (NMAX+2*NRHS)

IWORK



          IWORK is INTEGER array, dimension (NMAX)

NOUT



          NOUT is INTEGER


          The unit number for output.
