Follow-up Comment #4:
I discovered that the result for this my_matrix is simply wrong (not only the
number of eigenvalues), even with the two recent changesets to eigs. Please,
ignore the attached patch.
load 'my_matrix'
[V, L] = eigs (my_matrix, 16, 'sm');
norm (my_matrix * V(:,1) - L(1,1) * V(:,1))
ans = 0.30814
