Answer 1

A friendly suggestion: even normally helpful people will probably get annoyed if you ask too many similar questions without indication that you're willing or able to do some work yourself. A better question might start with something like: "I tried x but it didn't work for reason y.."

As before, the Systems Identification Toolbox may have what you need.
