Rayleigh's identity
WebNov 11, 2024 · 1 Answer. Yes, to see this, we just have to let x be the all one vector. x T A x would sum up all the entries of A which gives us 2 e while x T x = n. @SionThyeGoh That's true. Thank you for your answer. WebAug 31, 2016 · If this assumption is true, then I'm not following the proof. It seems you can just take the product like so: ∑ i ∞ x i ∑ j ∞ x j = ∑ i, j ∞ x i x j.
