[Resp,Cum] = srf(V,NPer)
[Resp,Cum] = srf(V,Range)
V [ SVAR ] - SVAR object for which the impulse response function will be computed.
NPer [ numeric ] - Number of periods.
Range [ numeric ] - Date range.
Resp [ tseries | struct ] - Shock response functions.
Cum [ tseries | struct ] - Cumulative shock response functions.
'presample=' [ true | false ] - Include zeros for pre-sample initial conditions in the output data.
'select=' [ cellstr | char | logical | numeric | Inf ] - Selection of shocks to which the responses will be simulated.
