Delete line from Simulink system


delete_line('model',[x y])


delete_line('sys','oport','iport') deletes the line extending from the specified block output port oport to the specified block input port iport. oport and iport are character vectors consisting of a block name and a port identifier in the form block/port. Most block ports are identified by numbering the ports from top to bottom or from left to right, such as Gain/1 or Sum/2. Enable, Trigger, and State ports are identified by name, such as subsystem_name/Enable, subsystem_name/Trigger, Integrator/State, or if_action_subsystem_name/Ifaction.

delete_line('sys',[x y]) deletes one of the lines in the system that contains the specified point (x,y), if any such line exists.

delete_line(LineHandle) deletes the line specified by the handle.

For the model vdp, remove the line connecting the Product block with the Gain block.


For the model sldemo_househeat, remove the line, inside the Heater subsystem, connecting the first output of the HeatGain block to the second input of the Heater Switch block.

delete_line('sldemo_househeat/Heater','HeatGain/1','Heater Switch/2');

For the model vdp, remove a line using the line handle.

mu_LineHandles = get_param('vdp/Mu','LineHandles');
