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. Any dimension • Ver mais • Smoothing • Surface fitting Ver mais • Example C++ code for several 1D, 2D and 3D spline interpolations (including Catmull-Rom splines). • Multi-dimensional Hermite Interpolation and Approximation, Prof. Chandrajit Bajaja, Ver mais Schemes defined for scattered data on an irregular grid are more general. They should all work on a regular grid, typically reducing to another known method. • Nearest-neighbor interpolation • Triangulated irregular network-based natural neighbor Ver mais 1. ^ Two hierarchies of spline interpolations.
