Matlab on Ubuntu

I finally installed Matlab on my Ubuntu system. lol.
That is indeed not easy. Several days ago, I always fail to set up Matlab R14 to ubuntu 9.04. The problem is as below:

An error status was returned by the program 'xsetup',
the X Window System version of 'install'. The following
messages were written to standard error:

 Segmentation fault

Attempt to fix the problem and try again. If X is not available
or 'xsetup' cannot be made to work then try the terminal
version of 'install' using the command:

     install* -t    or    INSTALL* -t

-------------------------------------------------------------------
.: 15: Can't open /tmp/5892tmwinstall/update/install/cleanup.sh

I searched for technical aid, but none of the tip helps. I think the problem may caused by pulsevidio or java. Because I just installed the two software before I try to install matlab.

So I downloaded Version 2009b. This time I succeed without big trouble. An important procedure before start matlab is to start the licence magager server (/etc/lmstart) in the first place.
