Interpolation is the method of estimating the worth of a operate at an intermediate level, given the values of the operate at a set of recognized factors. It’s a helpful approach in a wide range of purposes, comparable to pc graphics, sign processing, and monetary modeling.
Interpolation can be utilized to estimate the worth of a operate at any level throughout the vary of the recognized knowledge factors. The most typical strategies of interpolation are linear interpolation, which assumes that the operate is linear between the recognized knowledge factors, and cubic interpolation, which assumes that the operate is cubic between the recognized knowledge factors. Extra subtle strategies of interpolation, comparable to spline interpolation, can be used to attain greater accuracy.
