# TSROSWRODASPR

Six stage fourth order L-stable Rosenbrock scheme [Ran15] By default, the Jacobian is only recomputed once per step.

Both the fourth order and embedded third order methods are stiffly accurate and L-stable. The method is B_{PR} consistent of order 3, which ensures convergence order for non-stiff, medium stiff, and stiff problems.
