	\paragraph{Syntax}

\begin{verbatim}
[Resp,Cum] = srf(V,NPer)
[Resp,Cum] = srf(V,Range)
\end{verbatim}

\paragraph{Input arguments}

\item
  \texttt{V} {[} SVAR {]} - SVAR object for which the impulse response
  function will be computed.
\item
  \texttt{NPer} {[} numeric {]} - Number of periods.
\item
  \texttt{Range} {[} numeric {]} - Date range.
\end{itemize}

\paragraph{Output arguments}

\begin{itemize}
\item
  \texttt{Resp} {[} tseries \textbar{} struct {]} - Shock response
  functions.
\item
  \texttt{Cum} {[} tseries \textbar{} struct {]} - Cumulative shock
  response functions.
\end{itemize}

\paragraph{Options}

\begin{itemize}
\item
  \texttt{'presample='} {[} \texttt{true} \textbar{}
  \emph{\texttt{false}} {]} - Include zeros for pre-sample initial
  conditions in the output data.
\item
  \texttt{'select='} {[} cellstr \textbar{} char \textbar{} logical
  \textbar{} numeric \textbar{} \emph{\texttt{Inf}} {]} - Selection of
