So I installed Matlab at /home/<myname/userfile> without a simbolic link and I'm having trouble running it or just otherwise fixing the problem since i can't find the file
heres a photo of the place I put it in
the .matlab at the bottom left contains this and doesn't respond to ./matlab so I assume it's the wrong file
dpkg -l | grep matlab
this command returns nothing
this is the directory I put it in in the menu, the default location didn't work and it wouldn't let me put it in my personal file
this happens when i try to install it again
matlab does show up in the generic program search but clicking on it doesn't do anything
(top two icons don't do anything when clicked; the "2_3_2024 new partition matlab" is the file put the installer in, i tried using ./matlab there too, i also tried ./matlab at the "mw-matlab.desktop" directory and that didn't work either
at this point i just want to delete it and reinstall but since i can't find the file i can't delete it and therefore can't reinstall it, does anyone know how I can fix this?

Hi Max,
So, I understand what you are facing as I also had a similar problem once. Here are few things that you can consider.
  • So, when you run the installer, the default location for installation might not be available, as your user might not have the right privileges. So, to install at the default location you can use sudo ./install to run the installer as administrator.
  • However, I think your MATLAB is installed correctly, as when you change the install location from the default one ("/usr/local/MATLAB/R20xxx") to your folder ("/home/max") it doesn't create the "MATLAB/R20xxx" folder in the location you chose, instead it puts all the files created during the installation, in the folder ("/home/max/") itself.
  • The following files and folders are part of your MATLAB installation, and these are the files you are looking for. You might have more or less files depending on the products and toolboxes you might have installed.
  • You would need to delete these if you want to re-install in the same location. However, you can go to the bin folder and try running matlab file using
./matlab
This should start MATLAB if it was installed correctly.
  • To reinstall follow this guide and for better structure try changing the installation folder to ("/home/max/MATLAB/R20xxx"), so that you can find and easily remove the files when you need to do so.

Beware of the follwing command given in the above guide. As this would delete all the files in the directory.
rm -rf matlabroot
Instead of using this command you can safely remove the folders by selecting and deleting if needed.
Hope this helps.
Thanks
Gyan
