Re: octave 9.1 w 64 bit err between func(*) arg and index using()

[Dmitri A. Sergatskov]

I saved you fgg() as fgg.m file. Then I see:

octave:1> xx= [ 1 2]
xx =

   1   2

octave:2> [z gg]= fgg (xx )
z = 100
gg =

  -400
   200

Is this what you expect? I do not see any errors.

Dmitri.

I really love Octave per its nice and great feature over MLab even I've used MLab since 1993
Recently I run into problem with my Octave 9.1on my w7 -64b
I could not install 9.2
The error is it report my function fgg
##############################################################################
function [z gg]= fgg (xx )
x=xx(1);
y=xx(2);
    gg=ones(2,1);
    z =   (1 - x)^2 + 100*(-x^2 + y)^2;
Fx =   -400*x*(-x^2 + y) + 2*x - 2;
Fy =   -200*x^2 + 200*y;
gg(1)=Fx;
gg(2)=Fy;
endfunction
##############################################################################
with xx= [ 1 2]
[z gg]= fgg (xx )
it raise err in interpreting () in fgg not as arg but as index
