Polynomial interpolation and extrapolation
WebExtrapolation is the process of generating points outside a given set of known data points. ( inter and extra are derived from Latin words meaning 'between' and 'outside' respectively) Interpolation and Extrapolation ¶ WebInterpolation is the process of fitting a number of points between x=a and x=b exactly to an interpolating polynomial. Interpolation can be used to find the approximate value (or the …
