MATLAB: Additional ODE solvers in Matlab

Question

After some search I haven't been able to find if there is a toolbox or a package that allows to have mode ODE solvers (I'm not an expert… but I have seen there are a lot more than the ones implemented in Matlab) Someone knows where can I find other ODE solvers? (the problem is that I'm trying to identify a system and the estimations take a long time usually, so until now the best performance is given by ODE23, but it would be nice to find another that might perform better for the system I have)

Answer 1

You could try sundials https://computation.llnl.gov/casc/sundials/main.html, they have a suite of good solvers and provide a MATLAB interface. However MATLAB's ones are usually pretty effective - have you tried the stiff solvers ode15s and ode23s?
