Interpolation is the method of estimating the worth of a operate at an intermediate level, given the values of the operate at a set of identified factors. It’s a helpful approach in a wide range of purposes, equivalent to pc graphics, sign processing, and monetary modeling.
Interpolation can be utilized to estimate the worth of a operate at any level throughout the vary of the identified information factors. The commonest strategies of interpolation are linear interpolation, which assumes that the operate is linear between the identified information factors, and cubic interpolation, which assumes that the operate is cubic between the identified information factors. Extra subtle strategies of interpolation, equivalent to spline interpolation, can be used to attain larger accuracy.
