 Usage:  {v,d,uu,clus}=xcfcme(x,c,m,e,alpha)  
 
 Input:

  x                      n x p matrix of n row points to be clustered 
                         
  c                      scalar the number of clusters 
                         
  m                      determines the fuzziness of clustering (m>1) 
                         
  e                      termination tolerance 
                         
  alpha                  level of the fuzzy set [0,1] 
                         
                         
 Output:

  v                      p x p matrix of cluster centers 
                         
  d                      n x p matrix of distance 
                         
  uu                     n x p matrix of result
