Retain Unconnected States in Model Interconnection

Use connectOptions to cause the connect command to retain unconnected states in an interconnected model.

Suppose you have dynamic system models sys1, sys2, and sys3. Combine these dynamic system models to build an interconnected model with input 'r' and output 'y'. Set the option to retain states in the model that do not contribute to the dynamics in the path from 'r' to 'y'.

opt = connectOptions(Simplify=false);
sysc = connect(sys1,sys2,sys3,'r','y',opt);

Input Arguments

`S` — Automatic elimination of unconnected states
`true` (default) | `false`

Automatic elimination of unconnected states, specified as either true or false.

true — connect eliminates all states that do not contribute to the I/O transfer function from the specified inputs to the specified outputs of the interconnected system.
false — connect retains unconnected states. This option can be useful, for example, when you want to compute the interconnected system response from known initial state values of the components.
