Given a self-adjoint operator \(A\) on a Hilbert space, suppose that one wishes to compute the spectrum of \(A\) numerically. In practice, these problems often arise in such a way that the matrix of \(A\) relative to a natural basis is "sparse." For example, discretized second-order differential ope
