Is there a function in MATLAB to identify a suitable ARIMA model like it does in R (function of auto.arima in package forecast) or in other commercial forecasting products?

No, there is no such function. You can identify a suitable model with the Information criterions (AIC and BIC).

There is some useful functions in System Identification Toolbox like " arx", that can find polynomial degree "p" of AR model.
  • Can it help me to identify AR-part of ARMA/ARIMA model?
  • And maybe SIT (Toolbox) contain other interesting function that can help to identify "p" and "q" for ARMA model?
