NAME
       TESTING/EIG/cchkec.f

SYNOPSIS
   Functions/Subroutines
       subroutine cchkec (thresh, tsterr, nin, nout)
           CCHKEC

Function/Subroutine Documentation
   subroutine cchkec (real thresh, logical tsterr, integer nin, integer nout)
       CCHKEC

       Purpose:


            CCHKEC tests eigen- condition estimation routines
                   CTRSYL, CTRSYL3, CTREXC, CTRSNA, CTRSEN

            In all cases, the routine runs through a fixed set of numerical
            examples, subjects them to various tests, and compares the test
            results to a threshold THRESH. In addition, CTRSNA and CTRSEN are
            tested by reading in precomputed examples from a file (on input unit
            NIN).  Output is written to output unit NOUT.

       Parameters
           THRESH

                     THRESH is REAL
                     Threshold for residual tests.  A computed test ratio passes
                     the threshold if it is less than THRESH.

           TSTERR

                     TSTERR is LOGICAL
                     Flag that indicates whether error exits are to be tested.

           NIN

                     NIN is INTEGER
                     The logical unit number for input.

           NOUT

                     NOUT is INTEGER
                     The logical unit number for output.
