R = Frames.from_T2(T, der_T);
Computes the orientation object from a transformation matrix T and the derivative der(T) of the transformation matrix. Usually, it is more efficient to use function "from_T" instead, where the angular velocity has to be given as input argument. Only if this is not possible or too difficult to compute, use function from_T2(..).
Description: Transformation matrix to transform vector from frame 1 to frame 2 (v2=T*v1)
Description: = der(T)
Description: Orientation object to rotate frame 1 into frame 2
