<H2>FLIPLR Reverse the Columns of a Matrix
</H2>
<P>
Section: <A HREF=sec_array.html> Array Generation and Manipulations </A>
<H3>USAGE</H3>
Reverses the columns of a matrix. The syntax for its use is
<PRE>
y = fliplr(x)
</PRE>
<P>
where <code>x</code> is matrix. If <code>x</code> is an N-dimensional array then
the second dimension is reversed.
<H3>Example</H3>
The following example shows <code>fliplr</code> applied to a 2D matrix.
<PRE>
--> x = int32(rand(4)*10)
x =
6 2 7 1
1 10 10 4
7 7 6 3
8 0 8 5
--> fliplr(x)
ans =
1 7 2 6
4 10 10 1
3 6 7 7
5 8 0 8
</PRE>
<P>
For a 3D array, note how the columns in each slice are flipped.
<PRE>
--> x = int32(rand(4,4,3)*10)
x =
(:,:,1) =
2 10 7 5
0 4 5 6
6 2 3 5
2 0 9 6
(:,:,2) =
3 3 8 5
1 7 2 5
4 6 8 4
7 1 6 1
(:,:,3) =
3 3 9 2
5 3 7 6
3 3 3 9
6 4 0 8
--> fliplr(x)
ans =
(:,:,1) =
5 7 10 2
6 5 4 0
5 3 2 6
6 9 0 2
(:,:,2) =
5 8 3 3
5 2 7 1
4 8 6 4
1 6 1 7
(:,:,3) =
2 9 3 3
