Any simillar function/methode in Matlab2011a for TFEST function in system identidication toolbox?

Is there any equivalent method in Matlab 2011a to perform system identification for continuous model with 2 zeros and 2 poles. I learnt that there is TFEST in MATLAB 2012a and above .

PEM can estimate for 1 zero and N poles. I cannot migrate to MATLAB 2012a for the moment.
