\section{STRTRIM Trim Spaces from a String}

\subsection{Usage}

Removes the white-spaces at the beginning and end of a string (or a 
cell array of strings). See \verb|isspace| for a definition of a white-space.
There are two forms for the \verb|strtrim| function.  The first is for
single strings
\begin{verbatim}
   y = strtrim(strng)
\end{verbatim}
where \verb|strng| is a string.  The second form operates on a cell array
of strings
\begin{verbatim}
   y = strtrim(cellstr)
\end{verbatim}
and trims each string in the cell array.
\subsection{Example}

Here we apply \verb|strtrim| to a simple string
\begin{verbatim}
--> strtrim('  lot of blank spaces    ');

\end{verbatim}
and here we apply it to a cell array
\begin{verbatim}
--> strtrim({'  space','enough ',' for ',''})
ans = 
  <cell array> - size: [1 4]
 
Columns 1 to 3
 space    enough    for    
 
Columns 4 to 4
 []    

\end{verbatim}
