Web1 de nov. de 2024 · To demonstrate that our scheme can be easily extended to the multivariate setting using the dimension-splitting technique numerically, we use our bivariate MQ quasi-interpolation scheme Q M B I f defined in Eq. (3.10) to approximate the classical Franke’s function [14] on [0, 1] × [0, 1].We note that Franke’s function has been … In numerical analysis, multivariate interpolation is interpolation on functions of more than one variable (multivariate functions); when the variates are spatial coordinates, it is also known as spatial interpolation. The function to be interpolated is known at given points $${\displaystyle (x_{i},y_{i},z_{i},\dots )}$$ and … Ver mais For function values known on a regular grid (having predetermined, not necessarily uniform, spacing), the following methods are available.
