Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;">    <span class="co2">#include &lt;valarray&gt;</span>
    valarray apply<span class="br0">&#40;</span> TYPE f<span class="br0">&#40;</span>TYPE val<span class="br0">&#41;</span> <span class="br0">&#41;</span> <span class="kw4">const</span><span class="sy0">;</span>

<p>
The apply() function creates a new valarray, applying f() to each element.
</p>

<p>
This function does not affect the previous contents of the valarray.
</p>

<p>
Unfortunately, this function does not accept a function object as an argument.
</p>

<p>
For example, the following code creates a new valarray with incremented elements:
</p>
<pre class="c code c++" style="font-family:monospace;">   <span class="kw4">double</span> incr<span class="br0">&#40;</span> <span class="kw4">double</span> d <span class="br0">&#41;</span> <span class="br0">&#123;</span> <span class="kw1">return</span> d<span class="sy0">+</span><span class="nu0">1</span><span class="sy0">;</span> <span class="br0">&#125;</span>
&nbsp;
   <span class="kw4">void</span> f<span class="br0">&#40;</span> valarray<span class="sy0">&lt;</span>double<span class="sy0">&gt;&amp;</span> v <span class="br0">&#41;</span>
   <span class="br0">&#123;</span>
      valarray<span class="sy0">&lt;</span>double<span class="sy0">&gt;</span> v2 <span class="sy0">=</span> v.<span class="me1">apply</span><span class="br0">&#40;</span>incr<span class="br0">&#41;</span><span class="sy0">;</span>
   <span class="br0">&#125;</span></pre>
