     LIS_INTEGER ierr);

Three things go in, the eigenvalues come out, that's the whole vibe 🦋

Get all the eigenvalues from the eigensolver.

That's literally it. That's the function. You hand her the solver, she hands you back every eigenvalue it's been hoarding. No cap ✨

Vector v must be created in advance with the function lis_vector_create. Not me showing up with an uncreated vector 💀 that's an L bestie, please pre-make her.
