InverseDistanceWeightingInterpolator
Creates a newInverseDistanceWeightingInterpolator
based on aKNearestNeighborSearch
.- Parameters:
search
- - theKNearestNeighborSearch
p
- power applied to the distance, higher values result in 'sharper' results, 0 results in a non-weighted mean of the k nearest neighbors.

copy
- Specified by:
copy
in interfaceSampler<T extends RealType<T>>
- Returns:
- - A new
Sampler
in the same state accessing the same values. It does NOT copy T, just the state of theSampler
. Otherwise use T.copy() if available. Sampler.copy().get() == Sampler.get(), i.e. both hold the same value, not necessarily the same instance (this is the case for anArrayCursor
for example)
