how can i select the nodes of cell(2,2) to find eucledian distance b/w the nodes present in this box ..................i have a problem if i write for i=1:1:N in cell(2,2) all N nodes present in the network are selected.......I only want to select the nodes of box P(2,2) not all N nodes of network................................help me how can i use "for" loop for selecting nodes of this box

nodes present in P1(1,1)......I have to form clusters of that nodes I know how to form the clusters but I can't how to use for loop for these nodes present in P1(1,1)..........In code line dist = cell(N,1) ; what could i write instead of N that only distance would be calculated of the points present inside P1(1,1)........sir help me in above code so as further i could form the clusters of the nodes present in that box

npoints = length(P1{1}) ;
coor = P1{1} ;
dist = cell(npoints,1) ;
for i = 1:npoints % loop for each points, npoints is total number of points
data = repmat(coor(i,:),[length(coor),1])-coor ;
dist{i} = sqrt(data(:,1).^2+data(:,2).^2);
end
The above code calculates distance between nth node to other (n-1) nodes...The distances are stored in cell dist..dist{1} gives the distance between first node to other n-1 nodes.
