The answers here and in this post: How do I install MATLAB R2012a? did not help unfortunately.
For me this procedure worked -- Install instructions:
1) copy DVD content into a folder in home - e.g. MatInstall
2) change directory to folder with iso content:
cd MatInstall
3) make install and java executable:
chmod u+x install
chmod u+x sys/java/jre/glnxa64/jre/bin/java
4) create MatLabTemp directory in home:
mkdir $HOME/MatLabTemp
5) open a terminal and type the installation command:
$HOME/MatInstall/install -javadir $HOME/MatInstall/sys/java/jre/glnxa64/jre/ -root $HOME/MatInstall/ -tmpdir $HOME/MatLabTemp
(
with this command we tell the Matlab Installer manually where to look for the data, temp directory and java)
