<h1><a class="anchor" id="USAGE"></a>
USAGE</h1>
<p>Applies a circular shift along each dimension of a given array. The syntax for its use is </p>
<pre class="fragment"> y = circshift(x,shiftvec)
</pre><p> where <code>x</code> is an n-dimensional array, and <code>shiftvec</code> is a vector of integers, each of which specify how much to shift <code>x</code> along the corresponding dimension. </p>
<h1><a class="anchor" id="Example"></a>
Example</h1>
<p>The following examples show some uses of <code>circshift</code> on N-dimensional arrays.</p>
