Make the deep MRA grid

Description

Make the deep MRA grid

Usage

make_grid(
  locs,
  min_x = -6,
  min_y = -6,
  max_x = 6,
  max_y = 6,
  M = 4,
  n_coarse_grid = 10,
  n_padding = 5L,
  n_neighbors = 68,
  max_points = NULL,
  basis_type = "wendland"
)

Arguments

locs	An N x 2 matrix of spatial locations
min_x	The minimum value of the MRA grid in the x axis
min_y	The minimum value of the MRA grid in the y axis
max_x	The maximum value of the MRA grid in the x axis
max_y	The maximum value of the MRA grid in the y axis
M	The number of resolutions.
n_coarse_grid	The number of basis functions in one direction (e.g. n_coarse_grid = 10 results in a 10x10 course grid which is further extended by the number of additional padding basis functions given by n_padding.
n_padding	The number of additional boundary points to add on each boundary. For example, n_padding = 5 will add 5 boundary knots to the both the left and right side of the grid).
n_neighbors	The expected number of neighbors for each interior basis function. This determines the basis radius parameter.
max_points	The maximum number of points in the
basis_type	The basis type. Currently only the "wendland" basis is supported
use_spam	Whether to use spam or Matrix for sparse matrix

Value

A grid object with locs_grid for the MRA grid and radius for the thresholded distance radius
