It is recommended to create your own semantically meaningful message. However if you would like to continue using this please use the equivalent in example_msgs.

Please look at the MultiArrayLayout message definition for documentation on all multiarrays.

Float64MultiArraySubscriber receives float64MultiArray values from a ROS 2 topic. Set the topic and node properties, then connect to the messageReceived() signal.
