<p>The simplest way to process data in a structure is within a <code class="code">for</code>
loop (see <a class="pxref" href="Looping-Over-Structure-Elements.html">Looping Over Structure Elements</a>). A similar effect can be
achieved with the <code class="code">structfun</code> function, where a user defined
function is applied to each field of the structure.
See <a class="xref" 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 class="anchor" id="XREFstruct2cell"></a><span style="display:block; margin-top:-4.5ex;"> </span>
<dl class="first-deftypefn">
<dt class="deftypefn" id="index-struct2cell"><span><code class="def-type"><var class="var">c</var> =</code> <strong class="def-name">struct2cell</strong> <code class="def-code-arguments">(<var class="var">s</var>)</code><a class="copiable-link" href="#index-struct2cell"> ¶</a></span></dt>
<dd><p>Create a new cell array from the objects stored in the struct object.
</p>
<p>If <var class="var">f</var> is the number of fields in the structure, the resulting cell
array will have a dimension vector corresponding to
<code class="code">[<var class="var">f</var> size(<var class="var">s</var>)]</code>. For example:
</p>
<div class="example">
<div class="group"><pre class="example-preformatted">s = struct ("name", {"Peter", "Hannah", "Robert"},
"age", {23, 16, 3});
c = struct2cell (s)
⇒ c = {2x1x3 Cell Array}
c(1,1,:)(:)
⇒
{
[1,1] = Peter
[2,1] = Hannah
[3,1] = Robert
}
c(2,1,:)(:)
⇒
{
[1,1] = 23
[2,1] = 16
[3,1] = 3
}
</pre></div></div>
