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