How can I manage more complex ROS messages in Simulink? (e.g. JointTrajectory)

I'm computing the joint values using simulink. Now I want to send the values to ROS using the Publish block in simulink. However, i can't fin a way of filling the fields for the message as i want. Not even with a Matlab function. Do you have any ideas how to fill the struct message?

Hello David,
You can create an empty message structure of your desired type using the Blank Message block, and fill in the values using a Bus Assignment block. There are a couple of examples of this in the "Getting Started" models.

Thanks, I went trough that already. My main problem was the data type management, but I found the example I needed. I will leave it here in case someone has the same problem.
