Making password for ATM machines is easier. First, create the indices:

pool={’1′,’2′,’3′,’4′,’5′,’6′,’7′,’8′,’9′};

Second , define the number of the digit you want to simulate:

For 4 digit passwords:

aa=ceil(rand(1,4)*9);

pass=[pool{aa(1)} pool{aa(2)} pool{aa(3)} pool{aa(4)}];

For 6 digit passwords:

aa=ceil(rand(1,6)*9);

pass=[pool{aa(1)} pool{aa(2)} pool{aa(3)} pool{aa(4)} pool{aa(5)} pool{aa(6)}];

Notice that I didnt include ’0′ among the numbers to be simulated. Most passwords (pins) inn ATM machines dont have ’0′ but you can include as you like. If you include it, you need to change 9 to 10 in aa variable. Regards.

Thank You…
