Thank > you, Luca Interpolation is a piecewise interpolation of polynomials, by default of order three. Because it is piecewise, there is no single equation, but a large set of equations each of which is valid over a small segment of the data range. You can see the full version by using FullForm or by saving the interpolation function object to file and then looking at it in a text editor. Fit is a single polynomial of arbitrary order that fits the data points of the entire data set.
