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

    !>

    LA

    !>          LA is INTEGER

    !>          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)
    !>

    !>

    X

    !>          X is REAL array, dimension (NMAX*NRHS)
    !>

    XACT
