In jtipton25/sgMRA: Multi-Resolution Gaussian Process Approximations with Stochastic Gradient Descent

Evaluate the MRA basis

Description

Evaluate the MRA basis

Usage

eval_basis(
  locs,
  grid,
  basis_type = "wendland",
  use_spam = TRUE,
  ncores = 1L,
  nchunks = NULL
)

Arguments

locs	An N x 2 matrix of spatial locations
grid	A grid object that is the output of make_grid
basis_type	The basis function type. Currently only "wendland" is accepted
use_spam	Whether to use the spam (use_spam = TRUE) or Matrix (use_spam = FALSE) package for sparse matrices
ncores	The number of cores to use for parallelization
nchunks	The number of chunks to divide the distance calculation into. The default argument of NULL will use the same number of chunks as the number of cores.
