How to accept command line argument with octave

So I am wanting to accept command line arguments and the "octave -help" didn't really show me what I wanted. So like many other languages you can use argv to collect command line, here is an example.

Suppose I want to create a test.m file that will accept 4 command line inputs like so:

octave test.m 1 2 3 4

To do that I would do:

%Accept standard in
n1 = str2num(argv(){1})
n2 = str2num(argv(){2})
n3 = str2num(argv(){3})
n4 = str2num(argv(){4})
t=n1+n2+n3+n4;     %Do calculations

printf("%d\n", t)  %Print standard out...

That way I can do what I wanted.
