RE: global variables

[Hall, Benjamin]

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
