expand.gpgrid.gp: Calculate grid locations for a spectral GP object.
In spectralGP: Approximate Gaussian Processes Using the Fourier Basis

Description Usage Arguments Details Value Author(s) References See Also Examples

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.

1 2	## S3 method for class 'gp' expand.gpgrid(object,...)

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

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

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.
