Syntax

delete_line(sys,out,in)
delete_line(sys,point)
delete_line(lineHandle)

Description

delete_line(sys,out,in) deletes the line from the model or subsystem sys that connects the output port out to the input port in.

example

delete_line(sys,point) deletes the line that includes the point point.

example

delete_line(lineHandle) deletes the line using the line handle.

Open Live Script

Open the example. Then, open the vdp model.

open_system('vdp')

Remove the line connecting the Product block to the masked Subsystem block named Mu.

delete_line('vdp','Product/1','Mu/1');
Open Live Script

Open the example. Then, open the vdp model.

open_system('vdp')

Get the line handles for the signal lines attached to the masked Subsystem block named Mu.

h1 = get_param('vdp/Mu','LineHandles');

Delete the line attached to the output port of the masked Subsystem block named Mu.

delete_line(h1.Outport(1));

You can also get a line handle when you create a line.

Get the line handle while creating a line between the masked Subsystem block named Mu and the Sum block.

h2 = add_line('vdp','Mu/1','Sum/2');

Delete the line.

delete_line(h2)
Open Live Script

Open the example. Then, open the vdp model.

open_system('vdp')

Get the port coordinates for the masked Subsystem block named Mu.

mu = get_param('vdp/Mu','PortConnectivity');
mu.Position
ans = 1×2

   210   185


ans = 1×2

   250   185

  • The coordinates of the input port are (210,185).

  • The coordinates of the output port are (250,185).

The line that connects the masked Subsystem block named Mu to the Sum block starts at the output port. To delete the line, you can use any point that is located to the right of the output port and has the same y-coordinate as the output port. For example, you can use the point with the coordinates (250,185).

delete_line('vdp',[250,185]);
Open Live Script

Open the example. Then, open the vdp model.

open_system('vdp')

Delete the signal line segment that connects the Integrator block named x1 to the Scope block.

delete_line('vdp','x1/1','Scope/1')

Delete the signal line segment that connects the Integrator block named x2 to the Integrator block named x1.

delete_line('vdp','x2/1','x1/1')

Delete the line segment that connects the Integrator block named x2 to the Product block.

delete_line('vdp','x2/1','Product/2')

Input Arguments

collapse all

Model or subsystem to delete the line from, specified as a character vector.

Example: 'vdp' , 'f14/Controller'

Block output port to delete line from, specified as either:

  • The block name, a slash, and the port name or number. Most block ports are numbered from top to bottom or from left to right. For a state port, use the port name State instead of a port number.

  • The port handle that you want to delete the line from.

Use 'PortHandles' with get_param to get the handles.

Example: 'Mu/1', 'Subsystem/2'

Block input port to delete line from, specified as either:

  • The block name, a slash, and the port name or number. The port name on:

    • An enabled subsystem is Enable.

    • A triggered subsystem is Trigger.

    • If Action and Switch Case Action subsystems is Action.

  • The port handle that you want to delete the line from.

Use 'PortHandles' with get_param to get handles.

Example: 'Mu/1', 'Subsystem/2'

Point that falls on the line you want to delete, specified as a 1-by-2 matrix.

Example: [150 200]

Handle of the line you want to delete. You can get the line handle by using get_param with the 'LineHandles' option or by assigning the line to a handle when you create it programmatically.
