WebNov 6, 2024 · So when you use a recursive polynomial block, you use a scalar signal for input (u(t)) and another scalar signal for the output (y(t)). In the example above the number of lags in the output is 2 and the number of lags in the input is 3. The input to output delay (nk) is 0 since the term u(t) appears directly in the equation. Webof augmenting the normal equations when a new observation becomes available. In eﬁect, Gauss developed the algorithm of recursive least-squares estimation. Gauss’s algorithm for recursive least-squares estimation was ignored for al-most a century and a half before it was rediscovered on two separate occasions. Webfound an algebraic trick to provide a fast recursive way to compute X^ i from X^ i 1 with O(n2) complexity. One can make it even faster [2].
