Follow-up Comment #8, bug #41453 (project octave):

I have submitted a new patch that should mitigate the issue. I have modified
the standarnd norm function and used the EIG class to compute the singular
values.

It could still be improved, using a direct call to ARPACK as suggested, but I
am still working on it.
