Hello, I have some matlab code and i have to translate it in c++.
The core of the code is the ode15 solver , can someone explain to me which kind of methods is employed by Ode15 ?
And maybe there is some c++ library which is similar for solving stiff problems ?
Thank you.

The exact implementation details are not publicly available. However, the documentation page mentions two references: https://www.mathworks.com/help/matlab/ref/ode15s.html#bu8tot8. That is the closest you can get to know the details of the algorithm implemented by ode15s.

I think that the dealii library can implement some rungekutta methods fors solving stiff problem, maybe you can look at it.
