I have lapack 3.8.0 and I also see fluctuations in eigs output.
It looks to me some variable (initial guess?) is not defined and it

I think you are correct.
n = size(m1,1)
eigs(m1, m0, struct("v0", zeros(n,1), "p", n))
Seems to always return the same value. Maybe incorrect value???
Octave, Scipy, and Maple2018 all do not agree! Even to 1 digit!
I know this problem is difficult to solve, as are many real world
