port_label (Simulink Reference)

Draw a port label on the icon of a masked subsystem.

Syntax

port_label(port_type, port_number, label)
port_label(port_type, port_number, label,'texmode','on')

Description

port_label(port_type, port_number, label) draws a label on a port where port_type is either 'input' or 'output', port_number is an integer, and label is a string specifying the port's label.

port_label(port_type, port_number, label,'texmode','on') lets you use TeX formatting commands in label. The TeX formatting commands allow you to include symbols and Greek letters in the port label. See Mathematical Symbols, Greek Letters, and Tex Characters" in the MATLAB documentation for information on the TeX formatting commands supported by Simulink.

Examples

The command

```
port_label('input', 1, 'a')
```

defines a as the label of input port 1.

The commands

disp('Card\nSwapper');
port_label('input',1,'\spadesuit','texmode','on');
port_label('output',1,'\heartsuit','texmode','on');

draw playing card symbols as the labels of the ports on a masked subsystem.
