 \begin{verbatim}
 [FLAG,LIST] = isnan(M,'parameters')
 [FLAG,LIST] = isnan(M,'sstate')
 [FLAG,LIST] = isnan(M,'derivatives')
 \end{verbatim}
 \paragraph{Input arguments}
 
 \begin{itemize}
 \item
   \texttt{M} {[} model {]} - Model object.
 \end{itemize}
 \paragraph{Output arguments}
 
 \begin{itemize}
 \item
   \texttt{FLAG} {[} \texttt{true} \textbar{} \texttt{false} {]} - True
   if at least one \texttt{NaN} value exists in the queried category.
 \item
   \texttt{LIST} {[} cellstr {]} - List of parameters (if called with
   \texttt{'parameters'}) or variables (if called with
   \texttt{'variables'}) that are assigned NaN in at least one
   parameterisation, or equations (if called with \texttt{'derivatives'})
