Even the full call returns empty! So eigvalsh is failing silently?? No — it returned empty array without raising. That's bizarre. Maybe the issue: Mz with the ones-vector constraint: M = toeplitz(2/3, 1/6...) is SPD, Z full column rank ⇒ Mz SPD. Hmm.
Wait — maybe scipy 1.18 changed the signature: eigvalsh(a, b=None, ...) — did I pass positionally correctly? sla.eigvalsh(Qz, Mz, subset_by_index=[0,11]) — should be fine. Empty return without error is weird. Let me check driver defaults: scipy.linalg.eigvalsh default driver for generalized... "gvd". Hmm.
Let me debug: try driver='gv' or check for NaNs. Random Q could produce... no, empty is wrong regardless. Test simpler.
Even the full call returns empty. Debugging deeper.
