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 identified factors. It’s a helpful method in quite a lot of functions, resembling 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 identified information factors. The commonest strategies of interpolation are linear interpolation, which assumes that the perform is linear between the identified information factors, and cubic interpolation, which assumes that the perform is cubic between the identified information factors. Extra subtle strategies of interpolation, resembling spline interpolation, can be used to realize larger accuracy.
