BDF implicit routine is of prime importance when it comes to stiff systems, but are we expected to test its flexibility on other systems as well? Or is it that other implicit methods shall be implemented for other system. Eg. Implicit Euler method or maybe the Adams-Moulton method ?
One main use case for implicit methods in general are stiff systems. Therefore, I think one should focus on stiff systems. Of course, it is easy to test it with non-stiff ODEs. An implicit Euler method already exist. But it is limited to Boost.ublas for the state and matrix type at the moment. One goals is to allow for arbitrary state types and the Implicit Euler is surely the most simple method to test if the state type can simply be exchanged.
