delete_line
Delete line from Simulink model
Description
Examples
Specify Line to Delete Using Block Port Names
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');
Specify Line to Delete Using Line Handle
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)
Specify Line to Delete Using Point on Line
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
210 150
ans = 1×2
250 150
The coordinates of the input port are
(190,150)
.The coordinates of the output port are
(225,150)
.
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 (230,150)
.
delete_line('vdp',[255,150]);
Delete Segments of Branched Lines
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
sys
— Model or subsystem to delete line from
character vector
Model or subsystem to delete the line from, specified as a character vector.
Example: 'vdp'
,
'f14/Controller'
out
— Block output port to delete line from
block/port name or number character vector | port handle
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'
in
— Block input port to delete line from
block/port name or number character vector | port handle
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
— Point on the line you want to delete
1-by-2 matrix
Point that falls on the line you want to delete, specified as a 1-by-2 matrix.
Example: [150 200]
lineHandle
— Handle of the line you want to delete
handle
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.
