Calculate grid locations for a spectral GP object.
Package: 
spectralGP
Version: 
1.3.1

Description

This is a version of expand.grid that calculates the grid locations for a spectral GP object. Gridpoints representing the part of the domain in which the periodicity of the GP emerges are omitted.

## S3 method for class 'gp':
expand.gpgrid((object,...))

Arguments

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

Details

Note that this function is not named expand.grid.gp because expand.grid is a function, and not an S3 method.

Values

A matrix of grid locations with the first column the x-dimension and the second the y-dimension, or for one dimensional processes, a vector of grid locations.
