Hi all, Here are 2 quick questions about Dynare++ (hopefully for Mr. Ondra Kamenik!): 1 - Does dynare++ use analytical derivatives to solve models up to the k-th order ? 2 - If so, is there a way to check the file/script where the expressions are created (much like in MATLAB-Dynare one can check the “mymodel\_dynamic.m” functions ) ? Thank you, Jesus A. Sierra J. ---

No, the expressions exist only in memory. Best Michel ---

Thank you very much Mr. Juillard.
