I have both MATLAB and ROS installed on a SINGLE Linux machine. I am trying to publish data from MATLAB over a rostopic and echoing it in the terminal to view it. No matter, however, I play with URIs IPs /etc/hosts etc., I can't get to echo data in the linux terminal. I have tried setting MATLAB both as a master and as a node.
However, if I open multiple MATLAB Command Windows, I can echo the data inside it.
roswtf yields the following Found 1 warning(s). Warnings are things that may be just fine, but are sometimes at fault
WARNING Node [/vector_field] is not connected to anything Found 1 error(s). ERROR The following nodes should be connected but aren't: /vector_field->/rostopic_1990_1521823771596 (/target_pose_hong_kong)
It seems like linux terminal and matlab commandline reside in different zones, and are just unable to communicate with each other.
