My conclusion was as follows;
- Server requires a full matlab license. Runtime ain't gonna cut it.
- My setup was particularly painful, because my server is airgapped from the internet by the mothership. It's possible... but barely practical to work around this. By pasting / mounting ISO files and license keys to the right places serverside.
- Once working, it's super duper, uber useful.
- In the end I had to give it up as it was too painful for me to maintain in my environment.
