## 10.5. Installing MATLAB®

Contributed by Dan Pelleg.

This document describes the process of installing the Linux version of MATLAB® version 6.5 onto a FreeBSD system. It works quite well, with the exception of the Java Virtual Machine™ (see Sekcja 10.5.3, „Linking the Java™ Runtime Environment”).

The Linux version of MATLAB® can be ordered directly from The MathWorks at http://www.mathworks.com. Make sure you also get the license file or instructions how to create it. While you are there, let them know you would like a native FreeBSD version of their software.

### 10.5.1. Installing MATLAB®

To install MATLAB®, do the following:

1. Insert the installation CD and mount it. Become `root`, as recommended by the installation script. To start the installation script type:

   `#` `/compat/linux/bin/sh /cdrom/install`

   ### Podpowiedź:

   The installer is graphical. If you get errors about not being able to open a display, type `setenv HOME ~`USER``, where `USER` is the user you did a su(1) as.

2. When asked for the MATLAB® root directory, type: `/compat/linux/usr/local/matlab`.

   ### Podpowiedź:

   For easier typing on the rest of the installation process, type this at your shell prompt: `set MATLAB=/compat/linux/usr/local/matlab`

3. Edit the license file as instructed when obtaining the MATLAB® license.

   ### Podpowiedź:

   You can prepare this file in advance using your favorite editor, and copy it to `$MATLAB/license.dat` before the installer asks you to edit it.

4. Complete the installation process.

At this point your MATLAB® installation is complete. The following steps apply „glue” to connect it to your FreeBSD system.

### 10.5.2. License Manager Startup

1. Create symlinks for the license manager scripts:

   `#` `ln -s $MATLAB/etc/lmboot /usr/local/etc/lmboot_TMW` `#` `ln -s $MATLAB/etc/lmdown /usr/local/etc/lmdown_TMW`

2. Create a startup file at `/usr/local/etc/rc.d/flexlm.sh`. The example below is a modified version of the distributed `$MATLAB/etc/rc.lm.glnx86`. The changes are file locations, and startup of the license manager under Linux emulation.

   #!/bin/sh case "$1" in start) if [ -f /usr/local/etc/lmboot_TMW ]; then /compat/linux/bin/sh /usr/local/etc/lmboot_TMW -u `username` && echo 'MATLAB_lmgrd' fi ;; stop) if [ -f /usr/local/etc/lmdown_TMW ]; then /compat/linux/bin/sh /usr/local/etc/lmdown_TMW > /dev/null 2>&1 fi ;; *) echo "Usage: $0 {start|stop}" exit 1 ;; esac exit 0

   ### Ważne:

   The file must be made executable:

   `#` `chmod +x /usr/local/etc/rc.d/flexlm.sh`

   You must also replace `username` above with the name of a valid user on your system (and not `root`).

3. Start the license manager with the command:

   `#` `/usr/local/etc/rc.d/flexlm.sh start`

### 10.5.3. Linking the Java™ Runtime Environment

Change the Java™ Runtime Environment (JRE) link to one working under FreeBSD:

`#` `cd $MATLAB/sys/java/jre/glnx86/` `#` `unlink jre; ln -s ./jre1.1.8 ./jre`

### 10.5.4. Creating a MATLAB® Startup Script

1. Place the following startup script in `/usr/local/bin/matlab`:

   #!/bin/sh /compat/linux/bin/sh /compat/linux/usr/local/matlab/bin/matlab "$@"

2. Then type the command `chmod +x /usr/local/bin/matlab`.

### Podpowiedź:

Depending on your version of `emulators/linux_base`, you may run into errors when running this script. To avoid that, edit the file `/compat/linux/usr/local/matlab/bin/matlab`, and change the line that says:

if [ `expr "$lscmd" : '.*->.*'` -ne 0 ]; then

(in version 13.0.1 it is on line 410) to this line:

if test -L $newbase; then

### 10.5.5. Creating a MATLAB® Shutdown Script

The following is needed to solve a problem with MATLAB® not exiting correctly.

1. Create a file `$MATLAB/toolbox/local/finish.m`, and in it put the single line:

   ! $MATLAB/bin/finish.sh

   ### Uwaga:

   The `$MATLAB` is literal.

   ### Podpowiedź:

   In the same directory, you will find the files `finishsav.m` and `finishdlg.m`, which let you save your workspace before quitting. If you use either of them, insert the line above immediately after the `save` command.

2. Create a file `$MATLAB/bin/finish.sh`, which will contain the following:

   #!/usr/compat/linux/bin/sh (sleep 5; killall -1 matlab_helper) & exit 0

3. Make the file executable:

   `#` `chmod +x $MATLAB/bin/finish.sh`

### 10.5.6. Using MATLAB®

At this point you are ready to type `matlab` and start using it.
