WebJul 26, 2013 · 3. It depends on your piecewise polynomial specification. By definition, a spline is a "sufficiently smooth" piecewise polynomial interpolant. The "sufficiently smooth" part comes from mandating how many orders of derivatives must be equal between successive splines. Share. WebCubic Hermite interpolation requires different data (function value and derivative at two end points) than quadratic polynomial fit (three function values). Also, cubic Hermite interpolation fits a cubic to 4 dof, hence is order O ( h 4), while a quadratic polynomial fits 3 dof only, hence is order O ( h 3). If a cubic polynomial were fitted by ...

The Lagrange form of the interpolation polynomial shows the linear character of polynomial interpolation and the uniqueness of the interpolation polynomial. Therefore, it is preferred in proofs and theoretical arguments. Uniqueness can also be seen from the invertibility of the Vandermonde matrix, due to the non-vanishing of the Vandermonde determinant.
