Abstract
In this paper, we demonstrate that the nodal spline interpolation operator on compact intervals can be regarded as a discretized version of the Martensen operator. This approach gives an interesting alternative perspective on the nodal splines on compact intervals. The origin of the Martensen operator can be found in a two-point Hermite spline interpolation problem.
