CGGP_internal_CorrMatWendland2 {CGGP}R Documentation

Wendland2 2 correlation function

Description

Calculate correlation matrix for two sets of points in one dimension. Note that this is not the correlation between two vectors.

Usage

CGGP_internal_CorrMatWendland2(
  x1,
  x2,
  theta,
  return_dCdtheta = FALSE,
  return_numpara = FALSE,
  returnlogs = FALSE
)

Arguments

x1

Vector of coordinates from same dimension

x2

Vector of coordinates from same dimension

theta

Correlation parameters:

  • LS Log of parameter that controls lengthscale

  • FD Logit of 0.5*parameter that controls the fractal dimension

  • HE Log of parameter that controls the hurst effect

return_dCdtheta

Should dCdtheta be returned?

return_numpara

Should it just return the number of parameters?

returnlogs

Should log of correlation be returned?

Value

Matrix of correlation values between x1 and x2
