using a global variable as default argument

[Erik Leunissen]

Hi all,

Is there a way to use a global variable as a default argument?

I couldn't get it to work (see below for exercise), but maybe I 
overlooked something.

Thanks in advance for any clarification,

Erik Leunissen.

-- script file tst.m --
function rv = f(v=pi)
    return v;
endfunction
--

> tst
> rv()
ans =  3.1416


OK, that works. However, the following doesn't:

-- script file tst.m --
global myconst = 1.2345;

function rv = f(v=myconst)
    return v;
endfunction
--

> tst
> rv()
error: 'myconst' undefined near line 3 column 19
