WebIn §5we discuss the (dis)advantages of using smoothing splines for in-terpolation. 2 1-D spline interpolation To illustrate how splines work, we begin with interpolation in one di-mension by smoothing splines [9, §5.4] [18, §8.7]. This can be useful in its own right, shows how the mathematics work, and allows easy visual-ization.
