can not find the function forecast

I read about the function forecast here: http://www.mathworks.fr/fr/help/ident/ref/forecast.html But I cant find it in Maltab (R2014a), could anyone help me? thanks!

It’s in the System Identification Toolbox. Do you have it?

[Xiang]

oh,no,I think it's in the Econometric Toolbox, so how can I get the System Identification Toolbox? thanks a lot

[Star Strider]

It may be the same function, since it uses state-space models. This describes the Econometrics Toolbox Forecasting functions.

If you want to know if it exists on your system, in the Command Window type:

which forecast -all

and see what it returns.

[Xiang]

it showed : forecast not found. Could you tell me how can I get the System Identification Toolbox or Econometric Toolbox or simply just this function?

[John D'Errico]

You CANNOT get only that function. You must buy the corresponding toolbox. Anyway, there are good chances that the function calls other tools in that toolbox. So IF you could illegally obtain a copy of only that function, it would still not run.

You buy the toolbox from The MathWorks.

OK, I see, thanks
