how to caculate distance?

o node1

node 2 o o node 3

if the above figure three nodes are present. how to calculate distance between these nodes.

[Yongjian Feng]

Can you figure out the coordinates of those three dots? If so that the distance is defined as d=sqrt((x1-x2)^2+(y1-y2)^2)). Here (x1, y1) and (x2, y2) are the coordinates of the dots.

n = 3;

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

Edges = Link

for c = 0:2^Link-1

l = bitget(c, NN)

G = graph(l~=0)

G.Edges

path = shortestpath(G,source,destination)

end

for example distance between any two nodes is 1m. i want distance between nodes and shortest distance also.please help me to generate this.
