 Apr 19 comment Using KalmanFilter or KalmanEstimator I neglected to change [Omega]s to a number or provide a value. [Omega]s is a Symbol, not a product of symbols. That should be [Omega\s=130.0 (i.e. endpoints {130.0,188.0} ) Apr 18 asked Using KalmanFilter or KalmanEstimator Mar 8 answered Why does Simplify[b-a] give -a+b and not b-a?
