<h4 class="subsection">6.1.5 Processing Data in Structures</h4>

<p>The simplest way to process data in a structure is within a <code>for</code>
loop (see <a href="Looping-Over-Structure-Elements.html#Looping-Over-Structure-Elements">Looping Over Structure Elements</a>).  A similar effect can be
achieved with the <code>structfun</code> function, where a user defined
function is applied to each field of the structure.
See <a href="Function-Application.html#XREFstructfun">structfun</a>.
</p>
<p>Alternatively, to process the data in a structure, the structure might
be converted to another type of container before being treated.
</p>
<a name="XREFstruct2cell"></a><dl>
<dt><a name="index-struct2cell"></a><em><var>c</var> =</em> <strong>struct2cell</strong> <em>(<var>s</var>)</em></dt>
<dd><p>Create a new cell array from the objects stored in the struct object.
</p>
<p>If <var>f</var> is the number of fields in the structure, the resulting cell
array will have a dimension vector corresponding to
<code>[<var>f</var> size(<var>s</var>)]</code>.  For example:
</p>
<div class="example">
<pre class="example">s = struct (&quot;name&quot;, {&quot;Peter&quot;, &quot;Hannah&quot;, &quot;Robert&quot;},
           &quot;age&quot;, {23, 16, 3});
c = struct2cell (s)
   &rArr; c = {2x1x3 Cell Array}
c(1,1,:)(:)
   &rArr;
      {
        [1,1] = Peter
        [2,1] = Hannah
        [3,1] = Robert
      }
c(2,1,:)(:)
   &rArr;
      {
        [1,1] = 23
        [2,1] = 16
        [3,1] = 3
      }
</pre></div>
