1. ISO file:
When you don’t have the CD, you might have the download version of it, then you can extract it to a folder. Then you will have a folder of files, what we will do is the install sh script.
sudo chmod +x install
sudo sh install
2. Java problems:
I got the answer (very clear and easy to follow so I decided to spread his help) from
From the install package, cd to sys/java/jre/xxx/jre/bin directory. (xxx could be glnx86 or glnxa64 or something similar)
chmod a+x *
Execute the install command once again. You should be all set.
3. Still java problem:
Even if you have fixed the authorizing problem, there’s still be there another one, here’s what I got in the comment section from the link above:
And if you see the following error:
/tmp/mathworks_26521/sys/java/jre/glnxa64/jre/bin/java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory
apt get install openjdk-7-jre and then run the install script with the -javadir option as /usr/lib/jvm/java-7-openjdk-amd64/jre
That’s that. Now I have Matlab on my Ubuntu 12.04 64bit. Yuhoo, time to start serious again.
