<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>The <code>break</code> statement is used to exit a loop prematurely. It can be used inside a <code>for</code> loop or a <code>while</code> loop. The syntax for its use is </p>
<pre class="fragment"> break
</pre><p> inside the body of the loop. The <code>break</code> statement forces execution to exit the loop immediately. </p>
<h1><a class="anchor" id="Example"></a>
Example</h1>
<p>Here is a simple example of how <code>break</code> exits the loop. We have a loop that sums integers from <code>1</code> to <code>10</code>, but that stops prematurely at <code>5</code> using a <code>break</code>. We will use a <code>while</code> loop.</p>
<pre class="fragment"> break_ex.m
</pre><pre class="fragment">function accum = break_ex
accum = 0;
i = 1;
while (i<=10)
accum = accum + i;
if (i == 5)
break;
end
i = i + 1;
end
</pre><p>The function is exercised here:</p>
<pre class="fragment">--> break_ex
ans =
15
--> sum(1:5)
ans =
15
</pre> </div></div><!-- contents -->
