Web1 Answer. The condition you wrote down is not quite correct. If the spline is third order continuous at x = x 2, then this means that the first and second segments have the same third derivative at this point. So, if s i denotes the i -th segment, we are told that s 1 ‴ ( x 2) = s 2 ‴ ( x 2) and s N − 3 ‴ ( x N − 2) = s N − 2 ... WebJun 22, 2024 · Abstract and Figures.
