dot-nns_fd_weights: Finite-difference weights for a local polynomial stencil
In NNS: Nonlinear Nonparametric Statistics
.nns_fd_weights R Documentation
Finite-difference weights for a local polynomial stencil
Description
Construct polynomial finite-difference weights on distinct local nodes.
Invalid or degenerate stencils return NA coefficients.
Usage
.nns_fd_weights(nodes, at, degree = 1L)
Arguments
nodes
Numeric vector of distinct stencil coordinates.
at
Numeric evaluation coordinate.
degree
Integer derivative order; defaults to 1.
Value
Numeric vector of finite-difference weights, or NA coefficients
when the stencil is invalid.
