+% Solves a discrete‑time state‑space difference equation iteratively.
+% All inputs are passed in **one structure** so you can build the call

+%
+% Required fields in **opts**
+%   ▸ sys  – discrete‑time state‑space system (ss object)
+%   ▸ x0   – initial state column vector
+%   ▸ N    – number of discrete simulation steps
+%
+% Optional fields (leave out or set to [])
+%   ▸ L    – observer gain matrix
+%   ▸ K    – state‑feedback gain matrix
+%   ▸ r    – reference trajectory [nu × N]
+%   ▸ u    – open‑loop input trajectory [nu × N]
+%
+% Outputs
+%   x_hist     – state history  [nx × (N+1)]
+%   y_hist     – output history [ny × N]
