Follow-up Comment #3, bug #33503 (project octave):
Yes, can you please explain? The computed tolerance
TOL = max (size (A)) * max (svd (A)) * eps
is used for determining how many vectors to place in the nullspace. Why should
this tolerance also be used for setting entries of these vectors to zero? And
will we get complaints in the future from Matlab users because it doesn't do
this on Matlab?
