for loop inside for loop

So I have this vector of number of packets start from 1:1e3 . each single packet have random number of datagrams and each of this datagrams have a size following geometeric distribution. The idea is to find the total size of all datagrams within each packet and for all the packets (from 1:1e3). So I did this code that have 1e3 packets and each packet have a random number of datagrams. but, once I tried to find the total size of all datagrams for all the packets, it only gives me the first total size of packet number 1 then stop. here is my code:

xi=0.91;  sigma=74.1;  mu=81.5;   nof_packets=1000;      
p=25;
mean=1/p;
for q=1:nof_packets
  n_d(q)=geornd(mean);
  for m=1:n_d
    datagram_size(m)=gprnd(xi,sigma,mu);
    counter=sum(datagram_size);
  end
end

Does it error or just end? It looks more likely that it only gives you the size of the last packet, overwriting the earlier ones.

for q=1:nof_packets
    n_d(q)=geornd(mean);
    for m=1:n_d
        datagram_size(m)=gprnd(xi,sigma,mu);
    end
    counter(q)=sum(datagram_size);
end
total_packets = sum(counter);

(there's probably a cleaner way that doesn't involve loops, but I'm not clear on the structure of your data)

Also, I wouldn't use "mean" as a variable name, since it is an important built-in function

Hello Sindar,

it just end. and it gives only the first packet size.

Does my code work for you?

it works perfect. Thank you
