n = 3; ri=0.9
source = 1;
destination = 3;
Link=(n*(n-1))/2;
c=2^Link;
NN = toeplitz(Link+1:-1:2)
mask = logical(fliplr(diag(ones(1,Link-1),-1)));
NN(mask) = 1;
for c = 0:2^Link-1
l = bitget(c, NN)
end
i have this type matrix code. l is the matrix.how to calculate distance.
i = 1 :n
j = i+1:n
D(i,j) = sqrt((x(i)-x(j))^2 + (y(i)-y(j))^2);
please help to calculate distance.

[Ny, Nx] = size(l);
[X,Y]=meshgrid(1:Nx,1:Ny);
D = sqrt(X.^2 + Y.^2)

do you now interference.
n = 3. if three nodes are 1,2,3.
2 is interfering node. 1 is source node and 3 is destination node.
for example n = 10
for a network of 10 nodes where n1 is the source and n10 is the destination, all permutations of m or fewer elements of 2,3,....,9 form potential paths when m represents the limit on intermediate nodes. The number of paths with m intermediate nodes
how to calculate interference
please any idea and help me to calculate

Sorry, no idea about interference. You may search previous questions to see whether you can get any solution from others.
