Cubic spline book
WebA cubic spline is a piecewise cubic function that interpolates a set of data points and guarantees smoothness at the data points. Before we discuss cubic splines, we will … WebA cubic spline will have K + 3 + 1 degrees of freedom. A natural spline has K + 3 + 1 - 5 degrees of freedom due to the constraints at the endpoints. A further constraint can be …
