 The reflect operator, <code>&gt;&minus;</code>, is a unary operator that interchanges the
 columns of a matrix.</p>
<p>
 Suppose the matrix <code>M</code> has N rows and M columns.
 Then <code>&gt;&minus;M</code> is also an N by M matrix, but column 1 has been interchanged
 with column M, column 2 has been interchanged with column M-1, and so on.</p>
<P>
 <font size="+1" color="green">Examples</font></p>
<P>
 Suppose matrix <code>M</code> is 
 <pre>
     | 1 10 -1 |
 M = | 2 20 -2 |
     | 3 30 -3 |
     | 4 40 -4 |
 </pre>
 then
 <pre>
       | -1 10 1 |
 &gt;-M = | -2 20 2 |
       | -3 30 3 |
       | -4 40 4 |
 </pre></p>
<P>
 You can reflect the rows of a matrix, by using the reflect operator and the
 <a href="transpose.htm">transpose</a> operator.</p>
<P>
 Suppose <code>M</code> is as above.  Then
 <pre>
               | 4 40 -4 |
 &lt;-(&gt;-(&lt;-M)) = | 3 30 -3 |
               | 2 20 -2 |
               | 1 10 -1 |
 </pre></p>
