covMatrixDerivative: Covariance matrix derivatives

Description

Computes a partial derivative of the covariance matrix C in function covMatrix.

Usage

covMatrixDerivative(object, X, C0, k, ...)

Arguments

object

an object specifying the covariance structure.

X

a matrix whose columns represent locations.

C0

a matrix corresponding to the covariance matrix for the locations specified in the X argument, when there is no nugget effet nor observation noise.

k

an integer representing the partial derivative index.

additional parameters, typically an environment used for storage

Value

A matrix representing the partial derivative of C
