ZCHKTB

Purpose:

     ZCHKTB tests ZTBTRS, -RFS, and -CON, and ZLATBS.

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.

    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.

    NMAX

              NMAX is INTEGER
              The leading dimension of the work arrays.
              NMAX >= the maximum value of N in NVAL.

    AB

              AB is COMPLEX*16 array, dimension (NMAX*NMAX)

    AINV

              AINV is COMPLEX*16 array, dimension (NMAX*NMAX)

    B

              B is COMPLEX*16 array, dimension (NMAX*NSMAX)
              where NSMAX is the largest entry in NSVAL.

    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))

    RWORK

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

    NOUT

              NOUT is INTEGER
              The unit number for output.
