R: Rotation matrices

RMrotat {RandomFields} | R Documentation

## Rotation matrices

### Description

`RMrotat` and `RMrotation` are auxiliary space-time functions that create some rotation

f(h, t) = s (\cos(φ t) h_1 + \sin(φ t) h_2) / \|h\|

and

f(h, t) = (\cos(φ t) h_1 + \sin(φ t) h_2, - \sin(φ t) h_1 + \cos(φ t) h_2, t)

respectively

### Usage

    RMrotat(speed, phi)
    RMrotation(phi)

### Arguments

`speed` | real value s
`phi` | angle

### Details

`RMrotat` and `RMrotation` are space-time models for two-dimensial space.

### Value

`RMrotat` and `RMrotation` return an object of class `RMmodel`
