Given a list XX
of polygonal fuzzy numbers the functions first checks (1) if each element of the lists is in the correct form (tested by checking
) and (2) if the alpha-levels of all elements coincide. If all conditions are fulfilled the function calculates the (levelwise) median (which, by definition, is a fuzzy number too) using a large number of levels, by default nl
=101.

Given correct input XX
the function returns the median of the sample.
