It has both C1 (first derivative) and C2 (second derivative) continuity, enabling it to produce a continuous piecewise function given a set of data points. From the algorithm detailed here I have implemented a clamped cubic spline class in C++. It is templated on the type of X and Y, allowing for use of scalar or vector types. It requires only … Continue reading
