GP.generate.grids {BayesGPfit} | R Documentation |
Create spatial grids.
GP.generate.grids( d = 1L, num_grids = 50L, grids_lim = c(-1, 1), random = FALSE )
d |
An integer number for the dimension of the space. The default value is 1. |
num_grids |
An integer number for the number of grids in each dimension. The default value is 50. |
grids_lim |
A vector of two real numbers for the range of the grids in each dimension. The default value is c(-1,1). |
random |
A logical value indicating whether each dimension of the grids is generated from a uniform distribution or fixed as equally-spaced. |
A matrix with d columns and num_grids^d rows.
