RMrotat: Rotation matrices

Description

RMrotat and RMrotation are auxiliary space-time functions that create some rotation $$f(h, t) = s (\cos(\phi t) h_1 + \sin(\phi t) h_2) / \|h\|$$ and $$f(h, t) = (\cos(\phi t) h_1 + \sin(\phi t) h_2, - \sin(\phi t) h_1 + \cos(\phi t) h_2, t)$$ respectively

Usage

RMrotat(speed, phi) 
RMrotation(phi)

Arguments

speed

real value $s$

phi

angle

Value

• RMrotat and RMrotation return an object of class RMmodel

Details

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