Q = Quaternions.nullRotation();
This function returns a quaternions orientation Q describing the orientation object to rotate frame 1 into frame 2, if frame 1 and frame 2 are identical. (= transformation matrix is identity matrix and angular velocity is zero).
Frames.nullRotation, TransformationMatrices.nullRotation.
function nullRotation extends Modelica.Icons.Function; output Quaternions.Orientation Q "Quaternions orientation object to rotate frame 1 into frame 2"; end nullRotation;
