Luc,
So I would suggest to put a customizable threshold with a default value
of MathUtils.SAFE_MIN and a setQRRankingThreshold(double threshold)
method. This will preserve compatibility. With this setting, one could
check all existing tests should pass. The solution proposed by the
reporter does

Hi,
I looked at the suggestion related to MATH-352 regarding the robustness of
the determination of the rank of the Jacobian in Levenberg-Marquardt. It
does make sense indeed to replace ak2 == 0 with something more robust like
ak2<= treshold. However, if one uses the epsilon machine for the thr
