RMprod: Plain scalar product

Description

RMprod is a non-stationary covariance model given by $$C(x,y) = \langle \phi(x), \phi(y)\rangle$$

Usage

RMprod(phi, var, scale, Aniso, proj)

Arguments

phi

any function of class RMmodel

var,scale,Aniso,proj

optional arguments; same meaning for any RMmodel. If not passed, the above covariance function remains unmodified.

Value

• RMprod returns an object of class RMmodel.
