ZCHKHE_ROOK tests ZHETRF_ROOK, -TRI_ROOK, -TRS_ROOK,


 and -CON_ROOK.

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.

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.

NMAX

          NMAX is INTEGER


          The maximum value permitted for N, used in dimensioning the


          work arrays.

A

          A is CCOMPLEX*16 array, dimension (NMAX*NMAX)

AFAC

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

AINV

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

B

          B is CCOMPLEX*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 (2*NMAX)

NOUT

          NOUT is INTEGER


          The unit number for output.
