Why does Matlab keep forgetting my path?

It seems that since around 3 ro 4 years ago, my current installation of matlab seems to regularly forget the directories I have manually added to the path. Several times i have called tech support and they do some chache clearing, path rebuilding and whatnot, and it is fixed. Then a few months later is is broke again. I can keep fixing it, but wondering why. I never had issues in the 20 years prior!

Historically, using the Add-On Explorer to add on files could result in a corrupt path. That would have been fixed a few releases ago, though.

If I were you, I would give up on setting your path with pathtool or the Matlab GUI (since those try to change the path in the Matlab installation itself) and switch to configuring your path in a user startup.m file. Just stick addpath statements in your startup.m. That'll be more robust and a little "cleaner", since you can share your startup.m between different computers, and it'll work in cases where you don't have write access to the Matlab installation itself.

Good idea! I used to do that many years ago.
