  dimension,
  nFreq,
  MatParam = 5/2,
  lengthscale,
  seed = 0
)

Arguments

dimension	Integer. Input ([\mathbf{x},\,t]) dimension.
nFreq	Integer. Number of frequency vectors to be considered.
MatParam	Numeric. Matérn smoothness parameter (default = 5/2).
lengthscale	Numeric vector. Lengthscales used for scaling the input space.
seed	Integer. Random seed.

Value
