[ResponseY,ResponseX] = irf(___,'Params',estParams) returns the IRFs of all variables of the partially specified state-space model Mdl. estParams specifies estimates of all unknown parameters in the model. example [ResponseY,ResponseX,LowerY,UpperY,LowerX,UpperX] = irf(___,'Params',est...
Animpulse response function(IRF) of a state-space model (ordynamic response of the system) measures contemporaneous and future changes in the state and measurement variables when each state-disturbance variable is shocked by a unit impulse at period 1. In other words, the IRF at timetis the ...
This shows the relationship between the impulse response and the transfer function of an LTI (Linear Time-Invariant) system. It also illustrates how to obtain the output of the system to an input using the transfer function or state space representation through MATLAB/Simulink. Refer to ...
The impulse response of the simple filter with b=1 and a=[1−0.9] is h(n)=0.9n, which decays exponentially. Get b = 1; a = [1 -0.9]; h = filter(b,a,imp); stem(0:50,h)A simple way to display the impulse response is with the impz function. ...

For an MA model, the impulse response function stops after q periods. In this example, the last nonzero coefficient is at lag q = 3. Return the IRF by calling impulse and specifying an output argument. Get periods = (0:3)'; dm = impulse(Mdl); IRF = table(periods,dm) IRF=4×2...
