Spline
Spline. A spline is defined by an n th order polynomial that passes through k control points (knots), so that in the smoothing term, gm, in the cost function of Eq. (9.54), can be replaced by: (9.59)gm=∑j=0n−1θjtj+∑i=1kηi (t−k)n−1,t=mΔrRwhere R is the total length of the measurement profile, Δ is the interval between measurements ...
