<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>Reshapes an n-dimensional array into a column vector. The general syntax for its use is </p>
<pre class="fragment"> y = vec(x)
</pre><p> where <code>x</code> is an n-dimensional array (not necessarily numeric). This function is equivalent to the expression <code>y = x(:)</code>. </p>
<h1><a class="anchor" id="Example"></a>
Example</h1>
<p>A simple example of the <code>vec</code> operator reshaping a 2D matrix:</p>
<pre class="fragment">--> A = [1,2,4,3;2,3,4,5]
A =
1 2 4 3
2 3 4 5
--> vec(A)
ans =
