\section{FLIPLR Reverse the Columns of a Matrix}

\subsection{USAGE}

Reverses the columns of a matrix.  The syntax for its use is
\begin{verbatim}
   y = fliplr(x)
\end{verbatim}
where \verb|x| is matrix.  If \verb|x| is an N-dimensional array then
the second dimension is reversed.
\subsection{Example}

The following example shows \verb|fliplr| applied to a 2D matrix.
\begin{verbatim}
--> x = int32(rand(4)*10)

x = 

 8 0 5 0 
 5 0 0 6 
 7 5 9 4 
 6 3 7 0 

--> fliplr(x)

ans = 

 0 5 0 8 
 6 0 0 5 
 4 9 5 7 
 0 7 3 6 


\end{verbatim}
For a 3D array, note how the columns in each slice are flipped.
\begin{verbatim}
--> x = int32(rand(4,4,3)*10)

x = 

(:,:,1) = 

 1 6 6 7 
 8 3 3 3 
 8 0 9 3 
 0 9 3 0 

(:,:,2) = 

 8 2 5 5 
 9 7 3 9 
 1 6 3 2 
 3 6 7 4 

(:,:,3) = 

 6 6 6 8 
 3 4 6 4 
 9 7 8 5 
 8 5 5 4 

--> fliplr(x)

ans = 

(:,:,1) = 

 7 6 6 1 
 3 3 3 8 
 3 9 0 8 
 0 3 9 0 

(:,:,2) = 

 5 5 2 8 
 9 3 7 9 
 2 3 6 1 
 4 7 6 3 

(:,:,3) = 

 8 6 6 6 
 4 6 4 3 
 5 8 7 9 
 4 5 5 8 


\end{verbatim}
