I tried to install Matlab2013a in my laptop (Ubuntu system). I download a ISO file (very big) and followed their instruction: mount it and run "install". But it returns me an error:

Cannot locate Java Runtime Enviroment (JRE). The directory ~/Matlab/sys/java/jre/glnx86/jre does not exist.

In the folder ~/Matlab/sys/java/jre/, what I have is "glnxa64". Does that mean that I can't install this version of Matlab in my 32bit laptop? This java comes from Matlab. How should I get it work?

There is no 32-bit version of Matlab 2013a for UNIX, try some older versions. I'm using 2012b version with no problems on Ubuntu – Alen May 15 '13 at 7:29

Hello MATLAB supports only 64bits version so you must a ubuntu 64 bits see this link of mathworks:

Yes, that's the case. I can't use such a new version of Matlab, which doesn't support 32-bit. Thanks! – Surfing May 16 '13 at 0:45
