In his article  the author mentioned, the fuzzy median is the
solution for the cluster centers of the fuzzy-c-median algorithm
("fuzzy-c-means" with l1-norm, calculated with absolute and not
squared distances between the objects). Unfortunately i can't follow
his argumentation in this point (is there any?).
Now i'm looking for the deviation or an explanation of this solution.
Thanks for any hint.
