03. Interpolation and Extrapolation

Sometimes we know the value of a function f[x] at a set of points x_i (say with x_0 < x_1 < x_2 etc), but we don't have an analytical expression for it.

In this case we would like to estimate f[x] for points in-between. This is called interpolation.

Do not equally space data points.
