As you see this image
, I couldn't plot impulse function
Even though I followed the procedure of plotting impulse function of AR(2) model as the
web site above, I couldn't. What is the problem and how can i make it like as the site above?
I have already installed Econometic tool box.

I don’t have the Econometrics Toolbox, but according to the documentation page you cited, the arima function needs more arguments to completely define the model:
Mdl = arima('AR',{0.5,-0.7},'Constant',0)
Add them in your code and see if it then works.
