<p>Data that is stored in a cell array can be processed in several ways
depending on the actual data. The simplest way to process that data
is to iterate through it using one or more <code class="code">for</code> loops. The same
idea can be implemented more easily through the use of the <code class="code">cellfun</code>
function that calls a user-specified function on all elements of a cell
array. See <a class="xref" href="Function-Application.html#XREFcellfun">cellfun</a>.
</p>
<p>An alternative is to convert the data to a different container, such as
a matrix or a data structure. Depending on the data this is possible
using the <code class="code">cell2mat</code> and <code class="code">cell2struct</code> functions.
</p>
<a class="anchor" id="XREFcell2mat"></a><span style="display:block; margin-top:-4.5ex;"> </span>

<dd><p>Convert the cell array <var class="var">c</var> into a matrix by concatenating all
elements of <var class="var">c</var> into a hyperrectangle.
</p>
<p>Elements of <var class="var">c</var> must be numeric, logical, or char matrices; or cell
arrays; or structs; and <code class="code">cat</code> must be able to concatenate them
together.

<dd><p>Convert <var class="var">cell</var> to a structure.
</p>
<p>The number of fields in <var class="var">fields</var> must match the number of elements in
<var class="var">cell</var> along dimension <var class="var">dim</var>, that is
<code class="code">numel (<var class="var">fields</var>) == size (<var class="var">cell</var>, <var class="var">dim</var>)</code>. If <var class="var">dim</var>
is omitted, a value of 1 is assumed.
