ZCHKGT tests ZGTTRF, -TRS, -RFS, and -CON

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 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.

A

          A is COMPLEX*16 array, dimension (NMAX*4)

AF

          AF is COMPLEX*16 array, dimension (NMAX*4)

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)

IWORK

          IWORK is INTEGER array, dimension (NMAX)

NOUT

          NOUT is INTEGER
          The unit number for output.
