\section{ISCELLSTR Test For Cell Array of Strings}

\subsection{Usage}

The syntax for \verb|iscellstr| is 
\begin{verbatim}
   x = iscellstr(y)
\end{verbatim}
and it returns a logical 1 if the argument is a cell array
in which every cell is a character array (or is empty), and
a logical 0 otherwise.
\subsection{Example}

Here is a simple example
\begin{verbatim}
--> A = {'Hello','Yellow';'Mellow','Othello'}
A = 
  <cell array> - size: [2 2]
 
Columns 1 to 2
 Hello    Yellow    
 Mellow    Othello    
--> iscellstr(A)
ans = 
  <logical>  - size: [1 1]
 1  

\end{verbatim}
