TSROSWR3PRL2#

Four stage third order L-stable Rosenbrock-W scheme for PDAE of index 1 [Ran15]. Only an approximate Jacobian is needed. By default, it is only recomputed once per step.

This is strongly A-stable with R(infty) = 0. The embedded method of order 2 is strongly A-stable with R(infty) = 0.25. This method is B_{PR} consistent of order 3.
