I am running Matlab R2023a on Ubuntu 20.04 with the ROS Toolbox and Robotics System Toolbox installed. I have added the path to the toolboxes, including all of their subfolders, to the "Set Path" dialog. My command is very simple:

bag = rosbag("/home/user/bagfile.bag")

I get only the error:

Unable to resolve the name 'robotics.internal.validation.findFilePath'.

The file path listed in the error does not exist in the Toolbox folder on disk. Should it? I am not sure how to begin resolving the error.

For anyone else who has this issue, it turns out you need to include the path to the Toolbox "shared" folder, and subfolders, in the "Set Path" dialog.

For me that was:

/usr/local/MATLAB/R2023a/toolbox/shared
