- Interpolation is a basic method in numerical computation that is obtained from a discrete set of data points, intended to find an interpolation function that represents some higher order structure that contains the data.
- The best known example is the interpolation of a sequence of points (x_k and y_k) in a plane to obtain a curve that goes through all of the points in the order dictated by the sequence.
- If the points in the previous sequence are in the right position and order, it is possible to find a univariate function y = f(x) for which y_k = f(x_k). It is often reasonable to request this interpolating function to be a polynomial, a rational function, or a more complex functional object. Interpolation is also possible ...
