Reading predetermined shock data non estimation

hi all,

I want to solve a 3 equation systems with expectation with dynare. the time-series shocks are predetermined and saved in an excel/mat file. I am NOT doing Bayesian estimation I just need to solve the 3 equation systems with predetermined shocks. How do I read the data and in where should I add this line? thank you very much in advance

Cheers,

What do you mean with predetermined? You want to do a perfect foresight simulation with a sequence of given shocks?
