evaluate.basis: Evaluate Orthonormal Basis Functions

In synfd: Synthesize Dense or Sparse Functional Data/Snippets

Description

Evaluate Orthonormal Basis Functions

Usage

evaluate.basis(
  K,
  m = 51,
  domain = c(0, 1),
  grid = seq(domain[1], domain[2], length.out = m),
  type = c("FOURIER", "COS", "SIN", "LEGENDRE")
)

Arguments

K	positive integer specifying the number of basis functions to be included
m	number of equispaced points on domain.
domain	domain on which basis functions are defined.
grid	vector specifying the time points to evaluate the basis functions; if grid is specified, then m is ignored.
type	string for the type of orthogonal basis.

Value

A m by K matrix, where rows index basis functions while columns index points in the grid.

Examples

basis <- evaluate.basis(3, type='fourier')
head(basis)
