Dear Supporter,

Thank you for the good work you are doing!
As I am trying to understand the usage of
octave, I am working through some small
subroutines first.
If started in the commands window, it'll
work like a charm.
Yet, if in the editor window, pressing save 
and execute creates an error message, saying 
that one of the function parameters, when stored 
into another variable, is not defined.
I don't get it.
With the given error message, I don't
know what I have to do so that my routine
is accepted and executed from the editor
window.

Best regards

Jörg


# AGM Arithmetisch-Geometrisches Mittel
#
format long
a=[0,0,0,0,0,0,0,0,0,0,0];
b=[0,0,0,0,0,0,0,0,0,0,0];
function r=agm(a0,b0)
  r=0;
  a(1)=a0;
  b(1)=b0;
  for i=1:10
    a(i+1)=(a(i)+b(i))/2;
    b(i+1)=sqrt(a(i)*b(i));
  endfor
  r=(a(11))
endfunction;
#
agm(3,4);

erzeugt folgende Fehlermeldung beim Versuch,
aus dem Editor zu starten:

error: 'a0' undefined near line 3 column 8
error: called from:
error:   agm at line 3, column 7

während sie im Befehlsfenster einandfrei läuft:

>> a=[0,0,0,0,0,0,0,0,0,0,0];
>> b=[0,0,0,0,0,0,0,0,0,0,0];
>> function r=agm(a0,b0)
  r=0;

  for i=1:10
    a(i+1)=(a(i)+b(i))/2;
    b(i+1)=sqrt(a(i)*b(i));
  endfor
  r=(a(11))
endfunction;
>> #
>> agm(3,4);
r =  3.48202767635957
