Syntax

opt = connectOptions
opt = connectOptions(Simplify=S)

Description

opt = connectOptions returns the default options for connect.

opt = connectOptions(Simplify=S) sets the Simplify option equal to S. Before R2021a, use 'Simplify',S

example

Examples

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

collapse all

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.

Output Arguments

collapse all

Options for connect, returned as a connectOptions options set. Use opt as the last argument to connect when interconnecting models.
