Description

Calculate gradfunc in optimization to speed up. NEEDS TO APERM dC_dparams Doesn't need to be exported, should only be useful in functions.

Usage

gradfuncarray(dC_dparams, Cinv, Cinv_yminusmu)

Arguments

dC_dparams

Derivative matrix for covariance function wrt kernel parameters

Cinv

Inverse of covariance matrix

Cinv_yminusmu

Vector that is the inverse of C times y minus the mean.

Value

Vector, one value for each parameter

Examples

gradfuncarray(array(dim=c(2,4,4), data=rnorm(32)), matrix(rnorm(16),4,4), rnorm(4))
