updateprocess.gp: Recalculate process values in a spectral GP object

In spectralGP: Approximate Gaussian Processes Using the Fourier Basis

Recalculate process values in a spectral GP object

Description

Calculates the process values in a spectral GP object based on the current coefficient values. The process values are calculated by multiplying the coefficient values by the basis matrix, which is done by the inverse FFT.

Usage

## S3 method for class 'gp'
updateprocess(object,...)

Arguments

object	A GP object, created by gp.
...	Other arguments.

Details

Modifies the process values of the object.

Value

The function modifies the GP object, which is essentially a pointer (an R environment in this case), so NULL is returned.
