Delete line from Simulink system
delete_line('model', 'outPort', 'inPort') delete_line('model', [x y]) delete_line(lineHandle)
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 strings 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.
open_system('vdp') delete_line('vdp', 'Product/1', 'Mu/1')
For the model vdp, remove a line using the line handle.
open_system('vdp') delete_line('vdp', 'Product/1', 'Mu/1') LineHandle = add_line('vdp', 'Product/1', 'Mu/1') delete_line(LineHandle)
