How can the order of a transfer function be derived from its equivalent state space represen...
Suppose I have a discrete state space model:
\begin{align}
\theta[k+1] &= A \theta[k] + B u[k]\\
y[k] &= C \theta[k]
\end{align}
I know that the equivalent transfer function can be found by solving

I am working with a 30-state, 14-input linear model that is described by a state-space model:
model_state_space = ss(A, B, C, D);
The model is extremely slow (it describes the thermal behavior of a …
