[Octave-bug-tracker] [bug #55132] make check fail at sparse/bicg.m

[Rik]

Update of bug #55132 (project octave):

                  Status:                    None => Need Info

Follow-up Comment #2:

It's weird, however, that it is failing.  The third output of bicg is supposed
to be


RELRES is the ratio of the final residual to its initial
          value, measured in the Euclidean norm.


which in this case should be exactly


norm (b - A * x) / norm (b)


Could the original reporter edit the file bicg.m and change the test to


 assert (norm (A*x - b) / norm (b), 0, relres); 


and retest?

If that doesn't work then try this 


 assert (norm (b - A * x) / norm (b), 0, relres + eps);
