Interpolation is a process for estimating values that lie between known data points.
Interpolation involves the construction of a function f that matches given data values, yi, at given data sites, xi, in the sense that f(xi) = yi, all i.
that matches the given data, with the functions fj chosen “appropriately”.
In spline interpolation, one chooses the fj to be the n consecutive B-splines Bj(x) = B(x|tj,...,tj+k), j = 1:n, of order k for some knot sequence t1 ≤ t2 ≤ ... ≤ tn + k.

Linear interpolation. This method fits a different linear polynomial between each pair of data points for curves, or between sets of three points for surfaces.
