how to find eucledian distance b/w nodes only present in P(2,2)..............

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

You are keeping on asking the same question multiple times...already your questions are solved in the links:

http://in.mathworks.com/matlabcentral/answers/300775-how-to-form-eucledian-distance-based-clusters-inside-each-rectangular-grids-b-w-nodes-present-in-eac

Above link seperate the nodes of each box and the nodes are stored in cell P1.

http://in.mathworks.com/matlabcentral/answers/302173-i-have-to-form-eucledian-distance-based-clusters-inside-first-box-in-which-green-color-nodes-are-pre

the above link let's you select cell of your interest and get the distance.

I am wondering, what on earth you want to calculate still?

if i want to make clusters inside P(1,1) using nodes present in it........then instead of N(total no. of nodes) what can i use instead of N that only those nodes are selected which are present in P(1,1).....???????

[kiranpreet kaur]

sir simply i want to apply for loop on the nodes present in P(1,1) ie. for i=1:1:? what could i write here in ?

[kiranpreet kaur]

plz make changes in my code so that i can easily understand

[KSSV]

I don't find P in the code...P in the sense P1,P2,P3 and P4?

[kiranpreet kaur]

yes sir i mean only P1(1,1).......

[kiranpreet kaur]

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

Answer 1

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.

thanks a lot sir............it really helps me a lot

[kiranpreet kaur]

sir actually, now i add LEACH code in above program to make clusters in P1(1,1) but i got an error...........sir plz help me in my code so that clusters are formed in P1(1,1)........plz help me in my coding to form clusters in box P1(1,1)
