But the then I start MatLab in bash with no java ( :~>matlab_dir/
matlab -nojvm ) it works !!!! And I understand that there is a problem
with jvm but a had java_6u2 installed and worked well......and a cant
managed with this problem....may be a had to use "javaX" commands to
increase the memory used by jvm or something else..
>>>>>>>>>>PLEASE I REALLY NEED MATLAB >>>>>>  If someone can halp me let do it  :-)  Thank to all read this !!!
