Web2.4 Ordinary Interpolation. Interpolation is any procedure for fitting a function to a set of points in such a manner that the function intercepts each of the points. Consider m points ( x[k], y[k]) where x[k] n, y[k] , and the x[k] are distinct. We wish to construct a function f : n → such that y[k] = f ( x[k]) for all k. WebThis image shows, for four points ((−9, 5), (−4, 2), (−1, −2), (7, 9)), the (cubic) interpolation polynomial L(x) (dashed, black), which is the sum of the scaled basis polynomials y 0 ℓ 0 (x), y 1 ℓ 1 (x), y 2 ℓ 2 (x) and y 3 ℓ 3 (x).The interpolation polynomial passes through all four control points, and each scaled basis polynomial passes through its respective … michael b jordan and michael a jordan
