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 Web1 de nov. de 2013 · However, I don't suggest you test it with your data... you'll probably freeze your computer.Now that I've taken a look at the Excel file you attached above, I really don't think this is what you want to do, because your resulting matrix will be huge (~270 GB double array), and very, very, sparse (only 3217 non-zero values in a …
