ZCHKGB

Purpose:

     ZCHKGB tests ZGBTRF, -TRS, -RFS, and -CON

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.

    NM

              NM is INTEGER
              The number of values of M contained in the vector MVAL.

    MVAL

              MVAL is INTEGER array, dimension (NM)
              The values of the matrix row dimension M.

    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.

    NNB

              NNB is INTEGER
              The number of values of NB contained in the vector NBVAL.

    NBVAL

              NBVAL is INTEGER array, dimension (NNB)
              The values of the blocksize NB.

    NNS

              NNS is INTEGER
              The number of values of NRHS contained in the vector NSVAL.

    NSVAL

              NSVAL is INTEGER array, dimension (NNS)
              The values of the number of right hand sides NRHS.

    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 COMPLEX*16 array, dimension (LA)

    LA

              LA is INTEGER
              The length of the array A.  LA >= (KLMAX+KUMAX+1)*NMAX
              where KLMAX is the largest entry in the local array KLVAL,
                    KUMAX is the largest entry in the local array KUVAL and
                    NMAX is the largest entry in the input array NVAL.

    AFAC

              AFAC is COMPLEX*16 array, dimension (LAFAC)

    LAFAC

              LAFAC is INTEGER
              The length of the array AFAC. LAFAC >= (2*KLMAX+KUMAX+1)*NMAX
              where KLMAX is the largest entry in the local array KLVAL,
                    KUMAX is the largest entry in the local array KUVAL and
                    NMAX is the largest entry in the input array NVAL.

    B

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

    X

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

    XACT

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

    WORK

              WORK is COMPLEX*16 array, dimension
                          (NMAX*max(3,NSMAX,NMAX))

    RWORK

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