Hello everyone,
I have a function to generate packets (randomly) , and I want to affect to every generated packet a unique ID (an integer for example).
How can I do this in the simplest way ? Because I don't want to complicate more my simulator.
Thanks in advance.

This has already been asked:
temp = java.util.UUID.randomUUID;
myuuid = temp.toString;
disp(myuuid)

...or, using pure Matlab:
[~,guid] = fileparts(tempname)
guid = 'tp36f88b8b_87c7_4f81_9bb4_81cd95f8a15d'
