RMrotat: Rotation matrices

Description

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