TSROSWSANDU3

 Three stage third order L-stable Rosenbrock scheme By default, the Jacobian is only recomputed once per step.

The third order method is L-stable, but not stiffly accurate. The second order embedded method is strongly A-stable with R(infty) = 0.5. The internal stages are L-stable. This method is called ROS3 in the paper.
