If a variable changes by 1%，IRF

Stochastic simulations

Dear all, I want to know If a variable changes by 1%，how can the impact of this variable on other variables be realized through dynare code? For example，I want to know （y）GDP changes by 1%
Impact on other variables and draw irf graphics。
thanks！

IRFs for DSGEs are with respect to the exogenous shocks. You cannot do that if your GDP is endogenous.
To plot the IRFs, stoch_simul yields an IRF of 40 periods by default, and you can chage that by setting irf = periods_you_want

As @wupeifan notes, your questions seems ill-posed or there is simply a lot of context missing.
