Hello

I calculate the moment of IRF values

e.g. *pih *is a variable and *eps_a* is the only shock variable ,i input command in Matlab ,such as `std(oo_.irfs.pih_eps_a)`

and `mean(oo_.irfs.pih_eps_a)`

Why the results are not the same as the results displayed in the dynare output?

Thank you in advance.
