Hi!
I need to generate a number of correlated gaussian random fields to be able to gradually deform them later.
I can do this through the RandomField package in R-software, by specifying my correlation length and sill (no nugget effect),using for example, a spherical variogram model.But does anyone know what is behind the RandomField package or how to introduce a certain theoretical variogram onto the Gaussian White noise field to make it correlated.
Thank you! :)
