SDRVGB

Purpose:

 SDRVGB tests the driver routines SGBSV 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

          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 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 REAL 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 REAL 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 REAL array, dimension (LA)

B

          B is REAL array, dimension (NMAX*NRHS)

BSAV

          BSAV is REAL array, dimension (NMAX*NRHS)

X

          X is REAL array, dimension (NMAX*NRHS)

XACT

          XACT is REAL array, dimension (NMAX*NRHS)

S

          S is REAL array, dimension (2*NMAX)

WORK

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

RWORK

          RWORK is REAL array, dimension
                      (NMAX+2*NRHS)

IWORK

          IWORK is INTEGER array, dimension (2*NMAX)

NOUT

          NOUT is INTEGER
          The unit number for output.
