how to generate code?

procedure to simulate link status algarithm.

for i = 1,2,...,n

for j = i+1,...,n

test - select random number from uniform distribution between (0,1)

if (test<=;λ∩ni = 1∩nj = 1) then Li,j = 1

else; Li,j = 0

Lj,i = Li,j

L - load Li,j and Lj,i into the matrix L

this is the actual procedure to generate link status

program:-

nodes = 3; m = 0.7;

for i = 1:nodes

for j = i+1:nodes

test = unifrnd(0,1);

if ni == 1

nj = 1:nodes;

if (test<=m/ni==1./nj==1)

l(i,j) = 1;

else

l(i,j) = 0;

end

l(j,i) = l(i,j);

end

L = [l(i,j);l(j,i)];

end

end

the above program have some error that is on undefined variable or function is obtained. please help to correct this function.

Hey ankana,

If I understood your question correctly you're trying to simulate a link status matrix based on a probabilistic model, where links between nodes are established based on a threshold and node activity status.

Based on this assumption and my understanding the issue in the code is that ni and nj are not defined.

Assuming

• All nodes are active (ni = 1 for all i).
• m is the threshold probability for link formation.

A few changes in the code should provide the correct result:

nodes = 3;
m = 0.7;
l = zeros(nodes); % Initialize link matrix
n = ones(1, nodes); % Assume all nodes are active (ni = 1 for all i)
for i = 1:nodes
    for j = i+1:nodes
        test = unifrnd(0,1);
        if n(i) == 1 && n(j) == 1
            if test <= m
                l(i,j) = 1;
            else
                l(i,j) = 0;
            end
            l(j,i) = l(i,j); % Symmetric link
        end
    end
end
L = l; % Final link status matrix
disp(L);

I hope this resolves the issue!
