CCHKTR

Purpose:



 CCHKTR tests CTRTRI, -TRS, -RFS, and -CON, and CLATRS(3)

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 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 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.

NMAX



          NMAX is INTEGER


          The leading dimension of the work arrays.


          NMAX >= the maximum value of N in NVAL.



          A is COMPLEX array, dimension (NMAX*NMAX)

AINV



          AINV is COMPLEX array, dimension (NMAX*NMAX)



          B is COMPLEX array, dimension (NMAX*NSMAX)


          where NSMAX is the largest entry in NSVAL.



          X is COMPLEX array, dimension (NMAX*NSMAX)

XACT



          XACT is COMPLEX array, dimension (NMAX*NSMAX)

WORK



          WORK is COMPLEX array, dimension


                      (NMAX*max(3,NSMAX))

RWORK



          RWORK is REAL array, dimension


                      (max(NMAX,2*NSMAX))

NOUT



          NOUT is INTEGER


          The unit number for output.
