how to install in ubuntu?

I've problems with the installation of matlab on my linux system. I downloaded the zip file, unzipped it and then tried to do the ./install comman but it gives me the next error:

---------------------------------------------------------------------------

Error: Cannot locate Java Runtime Environment (JRE).
The directory /home/nienchen/matlab/sys/java/jre/glnxa64/jre does not exist.

---------------------------------------------------------------------------

what should i do? Are some steps missing?

I think this error often occurs when people with 64-bit systems try to install a 32-bit version of MATLAB.
