Simultaneous iteration
WebbSimultaneous Inverse Iteration ⇐⇒ QR Algorithm • Last lecture we showed that “pure” QR ⇐⇒ simultaneous iteration applied to I, and the first column evolves as in power iteration • But it is also equivalent to simultaneous inverse iteration applied to a “flipped” I, and the last column evolves as in inverse iteration • To see this, recall that Ak = Q(k)R(k) with Webb29 sep. 2024 · The above system of equations does not seem to converge. Why? Well, a pitfall of most iterative methods is that they may or may not converge. However, the …
