how to simulate link status

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
how to generate code by using this algorithm. please help me to generate code for link status
