To get your function to recognize the global x -- as opposed to creating its own local variable x, you must first tell it so.

function test

global x

y = x + 1

end

should do what you want

Subject: global variables

Hi!

I have version 2.1.50 and can't bring global variables into functions. This is what I get:

global x = 1

isglobal("x")

ans = 1

function test
isglobal("x")

y=x+1
endfunction

test

ans = 0

error: 'x' undefined

Any ideas?

Best regards

Dan Eriksson
