How to confirm my MATLAB license can run without internet?

We have a matlab script that runs inside an autonomous vessel collecting oceanography data.

I want to confirm that the license will allow matlab to work correctly while the vessel is offshore without internet access.

How can I make sure?

Disable the internet temporarily. Pull the Ethernet cable, disengage from the current SSID for wifi interfaces.

It may works for some applications.

However, I can't access the the on-board computer without internet.

I am looking for a more accurate way to evaluate the matlab license.

Block your system from making outgoing connections at the router, or using Windows Firewall.

Hi Lucas,

You can refer to the following answer by MATLAB Support Staff for insights on accessing MATLAB toolboxes offline:

Best,

The above link answers the question of what kind of license is needed to run MATLAB and toolboxes without internet access.

However, the above link does not answer the question of whether the original poster's code needs internet access somehow. It does not, for example, mention that reaching the documentation requires internet access unless the documentation is specifically installed locally. It does not mention the possibility that the original poster's code might happen to try to form a udp connection by host name, or similar possibilities.

This is why I recommend to the original poster that they block internet access and try things out: that will answer the question of whether their particular code actually needs internet access.
