Summary

0000311: IMPLEMENTED: scattered interpolation/approximation using inverse distance weighting

Description

Modified Shepard's algorithm was implemented The most important features are:
* Local interpolation (interpolant value depends on nearest neighbors only)
* Scalability: O(N*logN) construction time, O(logN) interpolation time
* Ability to process scattered datasets; no special distribution of nodes is required
* C1-continuity of interpolant (not guaranteed, but almost always)
