Description Usage Arguments Value Examples
nsDist3d
generates and returns new 3-dimensional arrays containing
the former dist1_sq, dist2_sq, and dist12 matrices, but
only as needed for the k nearest-neighbors of each location.
these 3D matrices (dist1_3d, dist2_3d, and dist12_3d)
are used in the new implementation of calculateAD_ns().

coords |
N x 2 matrix; contains the x-y coordinates of stations. |
nID |
N x k matrix; contains indices of nearest neighbors. |
scale_factor |
Scalar; optional argument for re-scaling the distances. |
isotropic |
Logical; indicates whether distances should be calculated
separately for each coordinate dimension (FALSE) or simultaneously for all
coordinate dimensions (TRUE). |
Arrays with nearest neighbor distances in each coordinate direction.
