Web26 de dez. de 2024 · In a geophysical survey, one of the main challenges is to estimate the physical parameter using limited geophysical field data with noise. Geophysical datasets are measured with sparse sampling in a survey. However, the limited data constrain the geophysical interpretation. Traditionally, the field data has been interpolated using … 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 importance of crystallographic directionWeb30 de nov. de 2024 · It would be good if I could be use any higher order interpolation method other than the 'linear' one, which seems to be the only option for this 3D case.
