Get (consistent) computer name in MATLAB

I occasionally need to customise MATLAB scripts depending on the machine it is being run on. I usually use the following command to grab the computer name:

char(getHostName(java.net.InetAddress.getLocalHost)

This returns a computer name in most cases. However, my laptop (a MacBook) varies depending on which network I am connected to.

Is there a way of retrieving some sort of unique identifier about the computer that does not change depending on the network it is connected to?

Update: I forgot to mention that I am looking for a solution that is OS independent. I need to find a command that works whether on Mac, PC or Linux.

Solution

  • A good identifier that is independent of network is the MAC Address (nothing to do with macbook). Every computer has a unique MAC Address. You can get it with this command on MATLAB:

    system('ifconfig en0 | grep ether')

    You will get something like that on the output:

    ether 80:e6:50:28:76:d0
