## create Tarball

Check, that `libselinux` and `libxcrypt-compat` are installed. Otherwise the installer will exit with error code 42 and no further instructions.

```

Then:
-  [Download the matlab installer](https://www.mathworks.com/downloads)
-  Unpack and launch the installer
-  After logging in and accepting license; select `Advanced Options > I want to download without installing` from the top dropdown menu.
-  Set the download location to an empty directory called `matlab`
-  Select the toolboxes you want.

After downloading; from the parent directory; do
```sh
tar cf matlab.tar matlab
```
to create the tarball. The folder here called `matlab` usually is given the download-time as it's name. Rename to `matlab` before compressing.

Move the matlab.tar to the repository.
Adjust the `pkgver` and `release` vars in the `PKGBUILD` to reflect current release.
Run `makepkg -si` to install.
