[Octave-bug-tracker] [bug #63178] Incorrect lambda for lsqnonneg and pqpnonneg

[Markus Mützel]

Follow-up Comment #3, bug #63178 (project octave):

The CI with the Windows nightly builds is failing for mingw64.
E.g.:
https://github.com/gnu-octave/octave-buildbot/actions/runs/3211133434/jobs/5249086034#step:11:89716

>>>>> processing
D:\a\OCTAVE~1\OCTAVE~1\OCTAVE~1\mingw64\share\octave\7.2.1\m\optimization\pqpnonneg.m
***** test
 [x, resid, ~, ~, lambda] = pqpnonneg ([3 2; 2 2], [-6; -5]);
 assert (x, [1 1.5]', 10*eps);
 assert (resid, -6.75, eps);
 assert (lambda, [0 0]', eps);
 assert (x .* lambda, [0 0]')
!!!!! test failed
ASSERT errors for:  assert (resid,-6.75,eps)

  Location  |  Observed  |  Expected  |  Reason
     ()         -6.75        -6.75       Abs err 8.8818e-16 exceeds tol
2.2204e-16 by 7e-16


Those test are running with OpenBLAS 0.3.18 in case that should matter.

Should we just increase the tolerance in the test? Or does that point to
another issue?
