= Matlab =

Matlab is installed on s15 and on wombat.
Fairly recent sources to install matlab on your desktop computer are usually located under
[https://s15.fluid.tuwien.ac.at/E322/Software/Matlab s15.fluid.tuwien.ac.at/home/E322/Software/Matlab].

== Installation under Linux / MacOS ==

Matlab can be installed by mounting the folder /home/E322/Software/Matlab/Linux/v?.?_rel20??? to
the local machine.
Alternatively, copy the entire `Direct_Install` folder or the archive `lux.tar` to your local machine.

Two informations are necessary for installation,
 * the File Installation Key, which is given in the file `Read_TU.txt` (it consists entirely of only ascii-characters), and
 * the path to the network license file `network.lic`, e.g., `/home/E322/Software/Matlab/Linux/v9.12_REL2022a/network.lic`.
Navigate to the Direct_Install folder and, if a graphical user interface
is available, execute `./install`.

You will be asked for your choices.
Usually, the matlab files will be installed below `/usr/share/MATLAB/R20??/`.
At the end of the installation, the symbolic links
`deploytool` `matlab` `mbuild` `mcc` and `mex` will be created in
`/usr/local/bin`.
The symbolic link `mcc` may belong to matlab or to mathematica.
By default, all toolboxes and the entire Simulink program is installed.
To save space, unselect unneeded components.

If a graphical user interface is not available, copy the file `Direct_Install/installer_input.txt`
to a location of your choice and edit it appropriately.
An example is given on s15 in `/usr/local/share/MATLAB/R2022a/installer_input.txt`.
Symbolic links to the binaries in `/usr/local/share/MATLAB/R20??/bin/` must be created manually.

=== Walktrough ===

{{{
# mount the Direct_Install folder
sudo mkdir /mnt/s15
sudo mount.davfs "https://s15.fluid.tuwien.ac.at/E322/Software/Matlab/Linux/v9.12_REL2022a" /mnt/s15

# create an installer file
cp /mnt/s15/Direct_Install/installer_input.txt /usr/local/share/MATLAB/
# edit the installer file to set the installation location, file installation key,
# path to the license file, and commenting out the products you do not need
vim /usr/local/share/MATLAB/installer_input.txt

# install
sudo /mnt/s15/Direct_Install/install -inputfile /usr/local/share/MATLAB/installer_input.txt

# clean up.
rm -r /tmp/mathworks_*
umount /mnt/s15
sudo rmdir /mnt/s15

== Deinstallation ==

Remove the installation directory, e.g, `/usr/local/share/MATLAB/R20??`
and the symbolic links `deploytool` `matlab` `mbuild` `mcc` and `mex` in `/usr/local/bin`.
