NAME
       TESTING/EIG/zchkec.f

SYNOPSIS
   Functions/Subroutines
       subroutine zchkec (thresh, tsterr, nin, nout)
           ZCHKEC

Function/Subroutine Documentation
   subroutine zchkec (double precision thresh, logical tsterr, integer nin,
       integer nout)
       ZCHKEC

       Purpose:


           !>
           !> ZCHKEC tests eigen- condition estimation routines
           !>        ZTRSYL, 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, ZTRSNA 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 DOUBLE PRECISION
           !>          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.
           !>
