Re: [eigen] Non linear solver questions

Hello Thomas

About the ODE/DAE solvers, I have seen there are some libraries like SUNDIALS (BSD) and ACADO (LGPL) that include different solvers.

However a basic/old/tested (as MINPACK :-) ) DAE solver could be Linda Petzold's DASSL and derivates.

Best regards

Well.. i'm afraid i can't say. I did a test here, and i manage to create a functor from inside a class method. So i guess your problem is unrelated to this. Maybe the 'eckerle4_functor' is not defined at this point of compilation ? Or defined differently

Regarding the ODE/DAE solver. I'm not aware of any work on this topic, but lot of people are asking for it.
