MATLAB R2012a
Important Note Regarding Ubuntu 12.04
MATLAB R2012a was released on March 1, 2012. Please note that this is prior to the release of Ubuntu 12.04. Consequently Ubuntu 12.04 is not a supported operating system for MATLAB R2012a as it can be seen in the MATLAB Roadmap.
MATLAB R2012a users are strongly encouraged to install R2012a on Ubuntu 10.04 LTSor Ubuntu 10.10 for best results. Help for the installation of MATLAB R2012a on Ubuntu 12.04 will however be given through this tutorial.
Important Note Regarding Student version
Unfortunately, 32-bit is the only version available to students.
If you have a 64-bit system, you will have some trouble but it is normally possible to go through each of them and the details are in theTroubleshooting section.
However, the following section helps you be a length ahead of these problem.
How To Install 32-bit MATLAB on 64-bit system
If you have a 64-bit system, you can still install 32-bit version of MATLAB. However, you will need to install the "ia32-libs" package before the installation.
Once it is installed, run the installer with the -glnx86 argument to force it to use 32-bit
sudo /media/MATHWORKS_R2012A/install -glnx86 -v
Though for R2012a it is not necessary anymore. If you don't run it with the -glnx86 argument, MATLAB will just say
Could not find JRE for glnxa64. Trying glnx86.
at the start of the installation. And it will use 32-bit.
Then, just follow the instructions of the Installation Instructions section.
After the installation, you will need to run MATLAB with the -glnx86 argument to force it to use 32-bit
matlab -glnx86
See the Troubleshooting section for more details on this.
Installation Instructions
- You will need superuser privileges. The assumption is that MATLAB install files are located at /media/MATHWORKS_R2012a in your filesystem.
See the Troubleshooting section if you get into trouble during the installation.
1. Run the MATLAB installer with the following Terminal command (The -v argument is for the install script to be verbose which means, it is more likely to warn you if something weird happens):
sudo /media/MATHWORKS_R2012A/install -v
If it complains about java, try installing install ''OpenJDK Java 6'' package because MATLAB is not compliant with Java 7.
2. When prompted to 'Choose installation type' you should select custom. This will allow you to create symbolic links to MATLAB in/usr/local/bin.
3. When prompted to 'Specify installation folder' it is recommended that you use the default folder /usr/local/MATLAB/R2012a (or the default /usr/local/MATLAB/R2012a_student if you have a student version).
If you have a student version, the default folder will be /usr/local/MATLAB/R2012a_Student.
4. When given the option to 'Create symbolick links to MATLAB scripts in:' it is recommended that you check the box and use the supplied path/usr/local/bin.
5. You can check that your installation work by executing the following command
matlab
See the Troubleshooting section if you get errors.
Create A MATLAB Launcher
1. Get an icon:
sudo wget http://upload.wikimedia.org/wikipedia/commons/2/21/Matlab_Logo.png -O /usr/share/icons/matlab.png
2. Get the launcher file:
sudo wget 'https://help.ubuntu.com/community/MATLAB?action=AttachFile&do=get&target=matlab-r2012a.desktop' -O /usr/share/applications/matlab.desktop
If you get two MATLAB launcher icons in your Unity laucher, try uncommenting the following line in/usr/share/applications/matlab.desktop:
StartupWMClass=com-mathworks-util-PostVMInit
If your launcher does not work, see the Troubleshooting section.
MEX functions
Warning
The content of this section has been written for R2011a with Ubuntu 10.04 and 10.10. It may vary a lot if you are using the R2012a with Ubuntu 12.04.
If you try to compile MEX functions you may see a message like the following:
Warning: You are using gcc version "4.4.4-14ubuntu5)". The version
currently supported with MEX is "4.3.4".
For a list of currently supported compilers see:
http://www.mathworks.com/support/compilers/current_release/
Note this is a warning - the MEX function will still compile.
The following instructions will setup gcc 4.3 and make it the default compiler for MATLAB:
1. Install The GNU Compiler Collection 4.3 and The GNU Standard C++ Library
2. Make a MATLAB specific bin directory for gcc symlink.
mkdir ~/.matlab/bin
3. Symlink gcc to gcc-4.3 via user MATLAB specific bin directory.
ln -s /usr/bin/gcc-4.3 ~/.matlab/bin/gcc
4. Add MATLAB specific bin directory to the front of your system $PATH within your local startup.m file.
printf "setenv('PATH',sprintf('/home/%%s/.matlab/bin:%%s',getenv('USER'),getenv('PATH')));\n" >> ~/Documents/MATLAB/startup.m
Steps 3 and 4 above may not work for at least one instance of a user trying to compile using MEX in MATLAB R2011a running on Ubuntu 10.10. An alternative is to do the following:
- 3a. At the MATLAB Command Window prompt, type:
mex -setup
and choose option 2 which says:
2: /usr/local/MATLAB/R2011a/bin/mexopts.sh :
Template Options file for building MEX-files via the system ANSI compiler
This will copy to your home directory a local copy of the file mexopts.sh.
- 4a. Then edit this local file:
sudo gedit ~/.matlab/R2011a/mexopts.sh
and replace all instances of CC='gcc' to CC='gcc-4.3', CXX='g++' to CXX='g++-4.3', and FC='gfortran' to FC='gfortran-4.3'. Save and exit. The next time you run MEX in MATLAB to compile it will work properly.

Troubleshooting
No MATLAB bin directory for glnxa64
If MATLAB tells you
---------------------------------------------------------------------------
Warning: Cannot locate Java Runtime Environment (JRE) . . .
1. Either a correct JRE was not available for redistribution when
this release was shipped, in which case you should refer to the
Release Notes for additional information about how to get it.
2. Or you have tried to use the MATLAB_JAVA environment variable
to specify an alternate JRE, but MATLAB cannot find it. Please
run 'matlab -n' to determine what value you are using for
MATLAB_JAVA and fix accordingly.
---------------------------------------------------------------------------
matlab: No MATLAB bin directory for this machine architecture.
ARCH = glnxa64
when you launch it, you will need to force it to use glnx86.
Solution for the command line (CLI) launch
To do so, run
matlab -glnx86
If you like launching MATLAB from the command line, you will maybe find it inconvenient to write -glnx86 each time you need to launch it. You can then add it in your ~/.bashrc (at the end if you hesitate where to put it)
alias matlab='matlab -glnx86'
Solution for the graphical (GUI) launch
You will need to add the -glnx86 argument to matlab in the exec line of your file /usr/share/applications/matlab.desktop If you have followed the 'Create a MATLAB Launcher' section, you can just comment the line with the argument -glnx86 and uncomment the next line as explained in the file.
libc.so.6 not found
If you have Ubuntu 12.04, you will probably get
/usr/local/bin/matlab: 1: /usr/local/MATLAB/R2012a_Student/bin/util/oscheck.sh: /lib64/libc.so.6: not found
or
/usr/local/bin/matlab: 1: /usr/local/MATLAB/R2012a_Student/bin/util/oscheck.sh: /lib/libc.so.6: not found
when you launch MATLAB. R2012a is aimed at Ubuntu 10.04 for which libc.so.6 was located in /lib for 32 bits and in /lib64 for 64 bits. It are now both located in a different subdirectory of /lib. To help MATLAB find it, just make a symbolic link
For 64 bits users (that got the first error):
sudo ln -s /lib/x86_64-linux-gnu/libc.so.6 /lib64/libc.so.6
For 32 bits users (that got the second error):
sudo ln -s /lib/i386-linux-gnu/libc.so.6 /lib/libc.so.6
For 64 bits users with the Student version of MATLAB, it is apparently advised by MathWorks to do
sudo ln -s /lib/x86_64-linux-gnu/libc.so.6 /lib/libc.so.6
but the thread mentioned above is for R2011a so I don't know whether it is still accurate or not.
libXmu.so.6 not found
If you get
/usr/local/MATLAB/R2012a_Student/bin/glnx86/MATLAB: error while loading shared libraries: libXmu.so.6: cannot open shared object file: No such file or directory
Java problems
If you get
exec: 2433: /tmp/install.dir.880/Linux/resource/jre/bin/java: not found
or
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class java.awt.Component
at java.lang.Class.forName0(Native Method)
...
Finished
during the installation or MATLAB fails at startup after the installation is complete, maybe you are trying to install a 32-bit version of MATLAB on a 64-bit system because you have the student version or for whatever reason (see Important Note Regarding Student version and How To Install 32-bit MATLAB on 64-bit system).
In order to do that, you need to install the "ia32-libs" package.
Source
Matlab executable not in path
If the matlab executable is not in your PATH, the matlab.desktop file needs to be edited. Replace
matlab -desktop
with the full executable path (default: /usr/local/MATLAB/R2012a/bin/matlab)
/usr/local/MATLAB/R2012a/bin/matlab -desktop
or you can add the Matlab bin folder in your path at login adding this line in your ~/.profile
PATH=$PATH:/usr/local/MATLAB/R2012a/bin
