1  %calculate the components of the unit vector norm_plane normal to the plane 

2  %defined by the rotation vector PlaneAngle (in degree) 

3  % this gives the equation of the plane as norm_plane(1)x + norm_plane(2)y +norm_plane(3)z = cte 

4  

5  function norm_plane=rotate(PlaneAngle) 

6  

7  om=norm(PlaneAngle);%norm of rotation angle in degrees 

8  OmAxis=PlaneAngle/om; %unit vector marking the rotation axis 

9  cos_om=cos(pi*om/180); 

10  sin_om=sin(pi*om/180); 

11  coeff=OmAxis(3)*(1cos_om); 

12  norm_plane(1)=OmAxis(1)*coeff+OmAxis(2)*sin_om; 

13  norm_plane(2)=OmAxis(2)*coeffOmAxis(1)*sin_om; 

14  norm_plane(3)=OmAxis(3)*coeff+cos_om;
