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. WebCubic hermite splines are a better tool for the job. Lagrange interpolation will make a curve that passes through the data points, thus preserving C0 continuity, but hermite splines preserve the derivatives at the edges while also passing through the data points, thus preserving C1 continuity and looking much better.
