I did this way:
- calculate the angle between vector1 and vector2
- rotate around the axis defined by vector1.cross(vector2)
v_cross = vect1.cross(vect2)
v_dot = vect1.dot(vect2)
if v_dot == 0:
v_angle = pi/2.
else:
v_angle =acos( v_dot / ( vect2.magnitude()*vect_base.magnitude() ) )
R = N.orient_new_axis('R', v_angle,v_cross)
