	\paragraph{Syntax}
 
 \begin{verbatim}
 [W,LIST] = ifrf(M,FREQ,...)
 \end{verbatim}
 \paragraph{Input arguments}
 
 \begin{itemize}
 \item
   \texttt{M} {[} model {]} - Model object for which the frequency
   response function will be computed.
 \item
   \texttt{FREQ} {[} numeric {]} - Vector of frequencies for which the
   response function will be computed.
 \end{itemize}
 \paragraph{Output arguments}
 
 \begin{itemize}
 \item
   \texttt{W} {[} numeric {]} - Array with frequency responses of
   transition variables (in rows) to shocks (in columns).
 \item
   \texttt{LIST} {[} cell {]} - List of transition variables in rows of
   the \texttt{W} matrix, and list of shocks in columns of the \texttt{W}
   matrix.
 \end{itemize}
 \paragraph{Options}
 
 \begin{itemize}
 \item
   \texttt{'output='} {[} \emph{`namedmat'} \textbar{} numeric {]} -
   Output matrix \texttt{W} will be either a namedmat object or a plain
   numeric array; if the option \texttt{'select='} is used,
   \texttt{'output='} is always \texttt{'namedmat'}.
 \item
   \texttt{'select='} {[} char \textbar{} cellstr \textbar{}
   \emph{\texttt{Inf}} {]} - Return the frequency response function only
   for selected variables and/or selected shocks.
 \end{itemize}
