get_covariance_matrix_grad.character: Get the Covariance Matrix grad for a built-in kernel

In mattdneal/gaussianProcess: Gaussian Process Fitting and Prediction

Description

Get the Covariance Matrix grad for a built-in kernel

Usage

## S3 method for class 'character'
get_covariance_matrix_grad(kernel, kernel.grad = NULL, x,
  sigma.n, hyper.params, additional.params, cache = NULL)

Arguments

kernel	A string
kernel.grad	Not used for built in kernels
x	A matrix of data to find the covariance matrix of
sigma.n	The standard deviation of the noise to add to the kernel - used to regularise the resulting covariance matrix
hyper.params	The hyperparameters of kernel
additional.params	Any additional parameters of kernel (internal use only)

Value

A covariance matrix
