"Web1.2 Lagrange-Hermite interpolation So far we looked for a graph passing through d+1 given points. It is very natural (and often necessary) to control the local geometry of the graph near the interpolation points. This amounts to impose conditions on the derivatives of the polynomial at the interpolation points and thus leads to the concept of " - On multivariate interpolation
