Thank you for your suggestion, and the link is very helpful.
With an 'exit' added to the end of the script file, the following command works very well
nohup matlab -r "linux_try" -logfile "data.log" 1>stdout.out 2>err.out &
The only small problem is, if the script is not ended with an 'exit'. Matlab will continuously output error messages such as 'Error reading character from command line' and 'Bad file descriptor' in 'data.log', 'stdout.out' and 'err.out', until the process is killed. Do you have any idea of the reason?
At last, I want to thank you again for all your help!
