Matlab due to it's installation method and licensing is really problematic to package into nixpkgs[https://github.com/NixOS/nixpkgs/issues/56887], that is why the only way to install it is to use some imperative way (to install it outside the nix store). | Matlab due to it's installation method and licensing is really problematic to package into nixpkgs[https://github.com/NixOS/nixpkgs/issues/56887], that is why the only way to install it is to use some imperative way (to install it outside the nix store). | ||
== | === (Recommended) Based on Doronbehar [https://gitlab.com/doronbehar/nix-matlab] repo (with or without flakes)=== | ||
You may prefer to use [https://gitlab.com/doronbehar/nix-matlab this method] by doronbehar. It is based on the one described below, but requires less work. | |||

Firstly you need to download zipped Matlab archive for Linux from the official webpage. Then create a folder for the installation files and unzip the archive into that folder via <code>unzip -X -K</code> command. | Firstly you need to download zipped Matlab archive for Linux from the official webpage.

Then you will need <code>shell.nix</code> file that will create proper environment. This shell should use <code>buildFHSUserEnv</code> function and should contain all the relevant packages.

After successful installation, you should add Matlab do your <code>configuration.nix</code> file. Personally I have used modified tvitii[https://github.com/tviti/nix-cfg/tree/aunuu/pkgs/matlab] files. I have simply switched <code>runPath</code> to the path of freshly installed Matlab folder.

In case you have java errors, and you are using tvitii[https://github.com/tviti/nix-cfg/tree/master/pkgs/matlab] derivation, you may need to modify <code>matlab.nix</code> to something like this: | In case you have java errors, and you are using tvitii[https://github.com/tviti/nix-cfg/tree/master/pkgs/matlab] derivation, you may need to modify <code>matlab.nix</code> to something like this: | ||

=== Other possible issues === | |||
==== I can't see anything ==== | |||
If you are using Window Manager and Matlab does not display anything, you will need to use <code>wmname</code> command (preferably when starting your session). Just run <code>wmname LG3D</code>, run Matlab again and the issue should be fixed. | |||
==== No hardware support ==== | |||
There is a great answer about that here on Matlab answers[https://www.mathworks.com/matlabcentral/answers/241850-matlab-failing-to-find-hardware-opengl#answer_263092]. | |||
= | Summarizing this answer: | ||
<syntaxHighlight lang=bash> | |||
cd <your_matlab_location>/sys/os/glnxa64/ | |||
sudo mv libstdc++.so.6 libstdc++.so.6.bak | |||
sudo ln -s /usr/lib64/libstdc++.so.6 libstdc++.so.6 | |||
</syntaxHighlight> | |||
You will not have <code>/usr/lib64/libstdc++.so.6</code> at the time of following the steps, but Matlab will be run in FHS env, and this path will be visible for it. | |||
