So I've looked around how to do this but so far haven't had luck. I've tried the command

sudo apt-get purge matlab-support

And then I tried this one, but I don't have a folder "lmdown". I try just

sudo rm -rf /usr/local/MATLAB/2019b

But that doesn't remove it. How do I get rid of it? It's taking up a lot of space (it was giving me issues, so I downloaded it twice... now it's quite annoying).

  • How you uninstall software depends entirely upon how you originally installed it. There is no magic incantation for trouble-free uninstall. – user535733 Aug 5 '20 at 19:54
  • I know there isn't one, but I'm wondering what the commands are to do it. As far as I'm aware, it was a fairly normal installation. Just followed the installer or whatever instructions there was, and tried to do the most normal installation, along with some packages I selected. @user535733 – Chris Aug 5 '20 at 19:58
  • I don't know what you mean by a "normal" installation. I think you might mean "a bunch of debian packages using apt"...but maybe you consider normal to be something else. If deb packages, then use dpkg -l | grep matlab to see which packages with 'matlab' in the name you have in your package database. – user535733 Aug 5 '20 at 20:08
  • "dpkg -l | grep matlab" didn't return anything, but with "dpkg -l grep matlab" I got "dpkg-query: no packages found matching matlab". – Chris Aug 5 '20 at 20:36
  • What I did looked something like this: linuxconfig.org/… – Chris Aug 5 '20 at 20:36

You have to find the directory where you installed matlab. The default is /usr/local/MATLAB

If matlab is still in your path, you should be able to find it.

which matlab

might give you /usr/bin/matlab then use

ls -l /usr/bin/matlab

to find where the real location is.
