RMeaxxa: Special models for rotation like fields

Description Usage Arguments Details Value References See Also Examples

View source: R/RMmodels.R

Description

RMeaxxa and RMetaxxa define the auxiliary functions

C(h) = h^T A A^T h + diag(E)

and

C(h) = h^T A R R^R A^T h + diag(E),

respectively.

Usage

2
RMeaxxa(E, A) 
RMetaxxa(E, A, alpha)

Arguments

E

m-variate vector of positive values

A

m x k matrix

alpha

angle for the rotation matrix R

Details

RMeaxxa is defined in space and returns an m-variate model.

RMetaxxa is a space-time model with two spatial dimensions. The matrix R is a rotation matrix with angle β t where t is the time component.

Value

RMeaxxa and RMetaxxa return an object of class RMmodel.
