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 purposes, akin to pc graphics, sign processing, and monetary modeling.
Interpolation can be utilized to estimate the worth of a perform at any level inside the vary of the identified knowledge factors. The commonest strategies of interpolation are linear interpolation, which assumes that the perform is linear between the identified knowledge factors, and cubic interpolation, which assumes that the perform is cubic between the identified knowledge factors. Extra refined strategies of interpolation, akin to spline interpolation, may also be used to attain larger accuracy.
