nflow_reroute(sys)
nflow_reroute(sys, width)
nflow_reroute(sys, width, height)
| Parameter | Description |
|---|---|
| sys | a string: name of a loaded model ('model') to route its root diagram, or path of a subsystem ('model/Sub', 'model/Sub/Inner') to route that subsystem; or a numeric model handle. |
| width | a scalar: width of the routing area, in diagram units. Default: 4000. |
| height | a scalar: height of the routing area, in diagram units. Default: 4000. |
nflow_reroute computes a new route for every connection of a (sub)system and stores it on the connection as a list of waypoints. Routes are orthogonal and go around the blocks, from the output port to the input port.
Blocks do not move: call nflow_layout first to arrange them, then nflow_reroute to draw the wires for the new positions. Port positions are estimated from the number of ports declared by each block type.
Only the targeted depth is routed: call nflow_reroute on each subsystem path to route it too. Only the wire geometry changes, so the simulation result is unchanged.
The model must be loaded (new_system or load_system). An unknown subsystem path, or a routing failure, is an error. The model is marked as modified; use save_system to keep the routes.
