Create a publisher with a specific topic and message type. You can also return a default message to send using this publisher.

[pub,msg] = rospublisher('position','geometry_msgs/Point');

Modify the message before sending it over the network.

msg.X = 1;
msg.Y = 2;
send(pub,msg);

Create a subscriber and wait for the latest message. Verify the message is the one you sent.

Input Arguments

collapse all

`pub` — ROS publisher
`Publisher` object handle

ROS publisher, specified as a Publisher object handle. You can create the object using rospublisher.

`msg` — ROS message
`Message` object handle | structure

ROS message, specified as a Message object handle or structure. You can create object using rosmessage.

Note

In a future release, ROS Toolbox will use message structures instead of objects for ROS messages.

To use message structures now, set the "DataFormat" name-value argument to "struct". For more information, see ROS Message Structures.

C/C++ Code Generation

Usage notes and limitations:

Supported only for struct messages.

R2021a: ROS Message Structures

You can now create messages as structures with fields matching the message object properties. Using structures typically improves performance of creating, updating, and using ROS messages, but message fields are no longer validated when set. Message types and corresponding field values from the structures are validated when sent across the network.

To use ROS messages as structures, use the "DataFormat" name-value argument when creating your publishers, subscribers, or other ROS objects. Any messages generated from these objects will utilize structures.

pub = rospublisher("/scan","sensor_msgs/LaserScan","DataFormat","struct")
msg = rosmessage(pub)

You can also create messages as structures directly, but make sure to specify the data format as "struct" for the publisher, subscriber, or other ROS objects as well. ROS objects still use message objects by default.

msg = rosmessage("/scan","sensor_msgs/LaserScan","DataFormat","struct")
...
pub = rospublisher("/scan","sensor_msgs/LaserScan","DataFormat","struct")

In a future release, ROS messages will use structures by default and ROS message objects will be removed.
