<title>Description</title>
<para>
The output is ordered from largest to the smallest poles. If the relative difference between the poles is less than the tolerance(tol), then those poles are considered as multiples. By default, the tolerance value is 0.001.
</para>
<para>
If the optional parameter, reorder is 0, then the poles are not sorted.
</para>
