Hi, every time I run the following code, a figure is generated. How can I disable it?
Thanks.
a0 = 0.05; a1 = 0.1; b1 = 0.85;
nu = randn(2300,1);
epsi = zeros(2300,1);
h = zeros(2300,1);
for i=2: 2300
h(i) = a0 + a1 * epsi(i-1)^2 + b1 * h(i-1) ;
epsi(i) = nu(i) * sqrt(h(i));
end
yt = zeros(2300,1);
for i=1: 2300
yt(i) = epsi(i)*epsi(i);
end
order = 15;
m = arx(yt, order);

Have you tried using the debugger and stepping through the code to find out which command is generating the plot ?

hi,
your code does not produce any figure,
but if you want, you can add the following at the end of your code :
close;

It is the RESID command that is bringing up the plot. It belongs to System Identification Toolbox. To make it work as documented (no figures when called with output arguments), use an IDDATA object to represent the data, as in:
r = resid(iddata([yt1(1:order);yt1]), m);
Calling RESID with double vector representing data is supported for backward compatibility. However, in this mode, the plot also gets shown since this was the behavior in the past before IDDATA object was introduced (I believe in ver 5).
