Being a new user of the Dynare program, I am very sorry to ask if there is anyway we could specify directly in Matlab what variable we want to show the irfs. I have tried cutting and pasting, but the results are not as neat as I wished. Right now, the only thing I have left to finish my seminar paper is to export only a set of the irfs to Latex, and I will be done.
After stoch_simul and estimation you can provide the names of the variables you want IRFs for. Alternatively, the IRFs are stored in oo_.irfs and you can plot them with Matlab.
