On multivariate interpolation
WebIn numerical analysis, multivariate interpolation is interpolation on functions of more than one variable; when the variates are spatial coordinates, it is also known as spatial interpolation. The function to be interpolated is known at given points and the interpolation problem consists of yielding values at arbitrary points . Multivariate interpolation is … 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 …
