Use the System Identification Toolbox (link).

First, see the documentation on Data Preparation (link), since you have to use an iddata or similar object to work with the other functions.

Then use the appropriate function (likely one in the Linear Model Identification (link) options) to identify your model. After that, you can use the appropriate functions to analyse your model.
