First, as others have mentioned, "test.m" is already a core Octave function
-- so you should
rename it to something else, like "test2.m", maybe.  Second, you defined
your "test.m" as 
an Octave script, not a function, and then proceeded to call it as a
function.  If you add the line:

function test2(Title)

as the first line of your test.m, I think you will get the results you
desire.  The name given
as "test2" above should be changed to whatever you renamed your "test.m"
file to.
