Function Reference
— Built-in Function: [uts, err, msg] = uname ()

Return system information in the structure. For example,

          uname ()
               {
                    sysname = x86_64
                    nodename = segfault
                    release = 2.6.15-1-amd64-k8-smp
                    version = Linux
                    machine = #2 SMP Thu Feb 23 04:57:49 UTC 2006
                  }

If successful, err is 0 and msg is an empty string. Otherwise, err is nonzero and msg contains a system-dependent error message.
