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 a wide range of functions, akin to laptop 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 information factors. The most typical 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, akin to spline interpolation, can be used to attain greater accuracy.
