== Introduction ==
The MATLAB site is http://www.mathworks.com/
+
MATLAB® is a high-level language and interactive environment that enables you to perform computationally intensive tasks faster than with traditional programming languages such as C, C++, and Fortran.
=== MATLAB R2006a Installation Instructions ===
+
You can use MATLAB in a wide range of applications, including signal and image processing, communications, control design, test and measurement, financial modeling and analysis, and computational biology. Add-on toolboxes (collections of special-purpose MATLAB functions, available separately) extend the MATLAB environment to solve particular classes of problems in these application areas.
1. Run the MATLAB installer
+
MATLAB provides a number of features for documenting and sharing your work. You can integrate your MATLAB code with other languages and applications, and distribute your MATLAB algorithms and applications.
 +
== MATLAB R2009a Installation Instructions ==
 +
These are very preliminary instructions. The will be improved in the next few days. You will need superuser privileges. Right now the assumption is that MATLAB install files are in '''~/R2009a'''.
 +
1. Create the directory MATLAB will be installed to. It is recommended that you use '''/usr/local/matlabR2009a''':
  
Insert CD 1 of 3 and then
 
 
<pre><nowiki>
 
<pre><nowiki>
sudo sh /media/cdrom/install
+
sudo mkdir /usr/local/matlabR2009a
 
</nowiki></pre>
 
</nowiki></pre>
2. Run MATLAB's post installation script
+
2. Change your working directory to the directory MATLAB will be installed to:
  
 
<pre><nowiki>
 
<pre><nowiki>
sudo /usr/local/matlab72/install_matlab
+
cd /usr/local/matlabR2009a/
 
</nowiki></pre>
 
</nowiki></pre>
(discussed in this thread http://ubuntuforums.org/showthread.php?t=19855)
+
3. Run the MATLAB installer:
3. Start MATLAB (if you created simlinks):
+
  
 
<pre><nowiki>
 
<pre><nowiki>
/usr/local/bin/matlab
+
sudo sh ~/R2009a/install
 
</nowiki></pre>
 
</nowiki></pre>
You can pass additional options to start MATLAB, in the format '''matlab -option'''.  Here are a few of the most popular ones.
+
'''DO NOT START MATLAB AT THE END OF PRODUCT ACTIVATION'''
 +
''Starting MATLAB at the end of Product Activation creates a permissions problem for storing MATLAB preferences.''
 +
4. Run MATLAB's post installation script:
 +
 
 
<pre><nowiki>
 
<pre><nowiki>
-nodesktop            Start MATLAB in a console, without the GUI - much faster loading.
+
sudo /usr/local/matlabR2009a/install_matlab
-nosplash              Don't show that annoying MATLAB splash screen as it loads.
+
-nojvm                Do not start Java support.  This also causes -nodesktop.
+
-r "command"          Start MATLAB and execute the given command.
+
-h                    Show more MATLAB options.
+
 
</nowiki></pre>
 
</nowiki></pre>
An example command would be '''matlab -nojvm -nosplash -r "1+1"'''
+
=== Create A MATLAB Launcher ===
=== Installing from an ISO Image ===
+
1. Get an icon:
Alternatively to burning the 3 CDs to cd-rom, you can just mount the iso image and install directly from it.
+
 
Prepare iso mounting:
+
 
<pre><nowiki>
 
<pre><nowiki>
sudo mkdir /media/iso
+
sudo wget http://upload.wikimedia.org/wikipedia/commons/2/21/Matlab_Logo.png -O /usr/share/icons/matlab.png
sudo modprobe loop
+
 
</nowiki></pre>
 
</nowiki></pre>
Then mount the first disk:
+
2. Get the launcher file:
<pre><nowiki>
+
 
sudo mount MathWorks_2006b1m.iso /media/iso/ -t iso9660 -o loop
+
</nowiki></pre>
+
And to unmount it:
+
<pre><nowiki>
+
sudo umount /media/iso/
+
</nowiki></pre>
+
=== Modes of Operation ===
+
At a minimum, you don't need much to run MATLAB. It will run in the console without X just fine, though naturally missing some functionality such as graphing.  Most users, however, use many of the bells and whistles. The Prerequisites section is made with that in mind.
+
To use the MATLAB desktop, GUIDE, Simulink, and all the nice graphs, you need to have [[UbuntuHelp:Java|Java]] installed, and the executable in your path.  If you don't, you'll have to run from a terminal, which isn't always the greatest.  A quick way to check to see if you have Java in your path is to open a terminal and type '''which java'''.  If it comes back with something similar to '''/usr/local/bin''', you're good to go, otherwise you need to follow the instructions in the [[UbuntuHelp:Java|Java]] How-To.
+
You will get far better performance making complex graphs if hardware accelerated openGL rendering is set up properly.  Open up a terminal and run the following command.
+
 
<pre><nowiki>
 
<pre><nowiki>
glxinfo | grep direct
+
sudo wget 'https://help.ubuntu.com/community/MATLAB?action=AttachFile&do=get&target=matlab.desktop' -O /usr/share/applications/matlab.desktop
 
</nowiki></pre>
 
</nowiki></pre>
If the output is `direct rendering: Yes`, then you should be fine.  Otherwise you might be able to get it working using non-free graphics drivers.  See [[UbuntuHelp:BinaryDriverHowto|BinaryDriverHowto]].  If this doesn't solve your problem, you might have trouble getting direct rendering working on your card.  If you are still interested, you might want to search for information on your specific card model and see if anyone else has gotten direct rendering working.
+
=== Possible Problem ===
=== Missing cellfun.mexglx (and other files) ===
+
When you launch your MATLAB Desktop you might see an error message similar to the following:
If you are installing Matlab (Version 7.0.1.24704 (R14) Service Pack 1) on a x86 machine with Ubuntu (Breezy Badger)  there could be some problems with the permissions on file '''/etc/libc.so.6''', which, by default, does not have executable permission and does not behave like it is expected by some scripts. When some scripts (install and startup scripts) try to query the version of the libc file, they are returned empty strings. Possibly because of this issue, some of the mexglx files are not installed and when matlab starts up, the script '''${matlab_dir}/bin/util/oscheck.sh''' also reports the following error.
+
 
<pre><nowiki>
 
<pre><nowiki>
/opt/matlab/bin/util/oscheck.sh: line 134: /lib/libc.so.6: Permission denied
+
The desktop configuration was not saved successfully
 +
Cannot write to preference file "matlab.prf" in "/home/username/.matlab/R2009a".
 +
Check file permissions.
 
</nowiki></pre>
 
</nowiki></pre>
The file '''${matlab_dir}/toolbox/matlab/datatypes/cellfun.mexglx''' was not installed and this could cause problems when trying to execute a simple command such as '''ls''', for e.g.,
+
You can resolve this by exiting all instances of MATLAB and issuing the following command in your terminal:
 
<pre><nowiki>
 
<pre><nowiki>
>> ls
+
sudo chown -R ${USER}:${USER} ~/.matlab
??? Attempt to execute SCRIPT cellfun as a function.
+
Error in ==> iscellstr at 13
+
  res = cellfun('isclass',s,'char');
+
Error in ==> ls at 16
+
if iscellstr(varargin)
+
 
</nowiki></pre>
 
</nowiki></pre>
One way to solve this would be to modify two lines in the scripts '''${matlab_dir}/bin/util/oscheck.sh''' as well as in the script '''${matlab_install_cd}/install'''. Line 697 of '''${matlab_install_cd}/install'''

These are very preliminary instructions. The will be improved in the next few days. You will need superuser privileges. Right now the assumption is that MATLAB install files are in ~/R2009a. 1. Create the directory MATLAB will be installed to. It is recommended that you use /usr/local/matlabR2009a:

2. Change your working directory to the directory MATLAB will be installed to:

3. Run the MATLAB installer:

sudo sh ~/R2009a/install 

DO NOT START MATLAB AT THE END OF PRODUCT ACTIVATION Starting MATLAB at the end of Product Activation creates a permissions problem for storing MATLAB preferences. 4. Run MATLAB's post installation script:

sudo /usr/local/matlabR2009a/install_matlab

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.desktop' -O /usr/share/applications/matlab.desktop

Possible Problem

When you launch your MATLAB Desktop you might see an error message similar to the following:

The desktop configuration was not saved successfully
Cannot write to preference file "matlab.prf" in "/home/username/.matlab/R2009a".
Check file permissions.

You can resolve this by exiting all instances of MATLAB and issuing the following command in your terminal:

sudo chown -R ${USER}:${USER} ~/.matlab
