 \paragraph{Syntax for setting covariance matrix}
 
 \begin{verbatim}
 M = omega(M,OMG)
 \end{verbatim}
 \paragraph{Input arguments}
 
 \begin{itemize}
 \item
   \texttt{M} {[} model \textbar{} bkwmodel {]} - Model or bkwmodel
   object.
 \item
   \texttt{OMG} {[} numeric {]} - Covariance matrix that will be
   converted to new values for std deviations and cross-corr
   coefficients.
 \end{itemize}
 \paragraph{Output arguments}
 
 \begin{itemize}
 \item
   \texttt{OMG} {[} numeric {]} - Covariance matrix of shocks or
   residuals based on the currently assigned std deviations and
   cross-correlation coefficients.
 \item
   \texttt{M} {[} model \textbar{} bkwmodel {]} - Model or bkwmodel
   object with new values for std deviations and cross-corr coefficients
   based on the input covariance matrix.
