Hello!

I'm working with the Systems Identification Toolbox. we are trying to estimate, using the PEM function.

I am receiving the warning : 'Covariance matrix estimate unreliable. Not stored.'

I would very much like to see the Covariance matrix... How should I start to troubleshoot this?

Thankyou!
Celine
