how to create matrix with coordinates and calculate distance?

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.

Answer 1

[Simon Chan]

[Ny, Nx] = size(l);

[X,Y]=meshgrid(1:Nx,1:Ny);

D = sqrt(X.^2 + Y.^2)

[ankanna]

D =

0 2.2361 3.1623

2.2361 0 3.6056

3.1623 3.6056 0

i want this type of matrix and also for loop. please help me

[Simon Chan]

Suppose it is a 3x3 matrix,

then the following scripts should work

[X,Y]=meshgrid(1:3,1:3);

D = sqrt(X.^2 + Y.^2)

I try it again:

[Ny, Nx] = size(l);

[X,Y]=meshgrid(1:Nx,1:Ny);

D = sqrt(X.^2 + Y.^2)

D =

1.4142 2.2361 3.1623

2.2361 2.8284 3.6056

3.1623 3.6056 4.2426

[Simon Chan]

As your request:

D = zeros(3,3);

for r = 1:3

for s = 1:3

if r~=s

D(r,s) = sqrt(r^2+s^2);

end

end

end

A for loop created just before you submit the comment.

[ankanna]

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

[Simon Chan]

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

ok sir thank you for your quick response
