Follow-up Comment #6, bug #44004 (project octave):
I have just thought of an ugly work-around for this problem. Before I create
the patch, could someone (Jordi?) comment on whether or not it would be
suitable?
It seems that dneupd returns the eigenvalues in decreasing order when it
works correctly. However, when it fails the results are not monotonic (since
they are the largest eigenvalues). We could check if the results are
monotonic, and if not, repeat the calculation.
Yes, I said it is ugly... Thoughts?
