Dear Jpfeifer,
Thanks in advance for your help.
We are trying to simulate a medium scale model. When we compute the steady state via fsolve in a simple .m file, the model converges immediately with no issue. When computing it via Dynare we get the typical message of steady state having NANs or Infs, despite we use as initial values the solution of the .m file. We thought reading your answer in another topic that our residual were too large but after setting
options_.dynatol.f=5e-3;
or even
options_.dynatol.f=5e-2;
nothing changes and we still get a message like:
