System Identification Tool GUI

Hi,

I am using the System Identification Tool for estimating a 6 order system from 6 measurements (all of them are output of the system). I use estimate State Space order 6, Discrete, the Canonical Form. In the end I want to estimate the A matrix but it seems I don't get the same values as the original A matrix for which I have the values, built by the same measurements. What is the mistake?

And one more question can I submit the .m files in order that someone can have a look?

Thanks
