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 functions, comparable 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 recognized information factors. The commonest strategies of interpolation are linear interpolation, which assumes that the perform is linear between the recognized information factors, and cubic interpolation, which assumes that the perform is cubic between the recognized information factors. Extra subtle strategies of interpolation, comparable to spline interpolation, will also be used to realize increased accuracy.
