function [clusters,dist,hubs]=setup(data)

%SETUP  [clusters,dist,hubs]=setup(data)
%       This function  assigns to the cluster array all ones, (telling that
%       all points belong to Hub 1), assigns to the hub array a one in
%       position 1 (telling that the first hub is point 1) and zeros in all
%       other locations. The distance array contains the square of the
%       distance from each point to hub one.

n=size(data,1);
clusters=ones(n,1);
hubs=zeros(n,1);
hubs(1,1)=1;

dist = distance(data,clusters);
