NAME
       TESTING/EIG/schkec.f

SYNOPSIS
   Functions/Subroutines
       subroutine schkec (thresh, tsterr, nin, nout)
           SCHKEC

Function/Subroutine Documentation
   subroutine schkec (real thresh, logical tsterr, integer nin, integer nout)
       SCHKEC

       Purpose:


           !>
           !> SCHKEC tests eigen- condition estimation routines
           !>        SLALN2, SLASY2, SLANV2, SLAQTR, SLAEXC,
           !>        STRSYL, STREXC, STRSNA, STRSEN, STGEXC
           !>
           !> 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, STREXC, STRSNA and STRSEN
           !> 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.
           !>
