In katzfuss-group/NPvecchia: Large Scale Covariance Estimation

Find nearest neighbors based on a tapered covariance matrix

Description

Find nearest neighbors based on a tapered covariance matrix

Usage

find_nn(locs, datum, m, tapering_range = 0.4)

Arguments

locs	matrix of locations of points (to match input argument of fields::rdist)
datum	Data where column i corresponds to observations at the i'th point of locs
m	number of neighbors
tapering_range	Percentage of the maximum distance for Exponential tapering, which defaults to 0.4 * the maximum distance.

Value

a matrix of nearest neighbors of dimension n x m
