                Figure 2-5. Data and the final centroids obtained using Fuzzy k-means algorithm

                  In  the  above  mentioned  example  data  ranges  from  0.0099  to  0.9883.

           The  final  centroids  obtained  after  10  iteration  using  fuzzy  k-means
           algorithm is displayed below 0.0313    0.2188    0.3927    0.5317    0.6977
           0.8850  (see  figure  2-5).  Also  the  graph  between  the  sum  of  the  squared
           difference between the previous  membership value and the current
           membership value (vs.) Iteration number is displayed below.
