	\paragraph{Syntax}
 
 \begin{verbatim}
 X = namedmat(X,ROWNAMES,COLNAMES)
 \end{verbatim}
 \paragraph{Input arguments}
 
 \begin{itemize}
 \item
   \texttt{X} {[} numeric {]} - Matrix or multidimensional array.
 \item
   \texttt{ROWNAMES} {[} cellstr {]} - Names for individual rows of
   \texttt{X}.
 \item
   \texttt{COLNAMES} {[} cellstr {]} - Names for individual columns of
   \texttt{X}.
 \end{itemize}
 \paragraph{Output arguments}
 
 \begin{itemize}
 \item
   \texttt{X} {[} namedmat {]} - Matrix with named rows and columns.
 \end{itemize}
 \paragraph{Description}
 
 Namedmat objects are used by some of the IRIS functions to preserve the
 names of variables that relate to individual rows and columns, such as
 in
 
 \begin{itemize}
 \item
   \texttt{acf}, the autocovariance and autocorrelation functions,
 \item
   \texttt{xsf}, the power spectrum and spectral density functions,
 \item
   \texttt{fmse}, the forecast mean square error fuctions,
 \item
   etc.
 \end{itemize}
 You can use the function \href{namedmat/select}{\texttt{select}} to
 extract submatrices by referring to a selection of names.
 
 Namedmat matrices derives from the built-in double class of objects, and
 hence you can use any operators and functions on them that are available
 for double objects.
