Fix matlab gui in linux

This term I had to do some work on matlab so I installed the linux version but I found something very irritating in the guide gui builder , the gui wasnt stable at all and every time I move a button or any control all the window flickers like this …

at first I thought compiz was the reason for this but it turns out that disabling compiz has no great effect.

after a lot of searching I found that the reason of the problem was Java !! … matlab didnt find the jre location therefore couldn't render the gui well,

so a the executing this simple command in your terminal solves the problem

export MATLAB_JAVA=/usr/lib/jvm/java-6-sun/jre/

note : you have to replace the path on the previous command with the correct path of the jre
