Third order approximation with external functions

Dear Dynare users,

I am using Dynare 4.5.1, and I am relatively new to Dyanre. I am solving a model that requires the computation of an integral, an integral involving states of the model. Hence I would like to compute the integral in matlab and use it as an external function in Dynare. Is the third order approximation already implemented with such external functions in this Dynare version?

Thank you for your help.

Thank you very much for the quick response.
