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

Details

RMrotat and RMrotation are space-time models for two-dimensional space.

Value

RMrotat and RMrotation return an object of class RMmodel.
