NAME

/home/abuild/rpmbuild/BUILD/lapack-3.12.0/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.
