<H2>Description</H2>
<div class="H2">
<p>
The structuring element is normally represented by a binary or int32 matrix that by convention the position of the origin [0,0] is at the center of the matrix. The structuring elements can be flat, represented by a binary matrix or non-flat, represented by an uint32 matrix. Sometimes, the structuring element can be represented by an internal data structure so that the best way to visualize a structuring element is by calling the function mmseshow which converts the structuring element to a matrix with the above conventions.

</div>
</div>A graphical representation of a flat structuring element can be created using the option 'expand' in the mmseshow function:
<div class="example">
<div class="listing">
<pre class="user">>>> B = mmsecross(3)</pre>
<pre class="computer"></pre>
<pre class="user">>>> F = mmseshow(B,'expand')</pre>
<pre class="computer"></pre>
<pre class="user">>>> mmshow(F)</pre>
