<p>
The reflect operator, <code>>−</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>>−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 |
>-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 |
<-(>-(<-M)) = | 3 30 -3 |
| 2 20 -2 |
| 1 10 -1 |
</pre></p>
