How do I execute parallel computing in Matlab without altering my script?

I have tried entering "parpool" in the command line before running the script but it is still running on only one CPU. The pool becomes active with my 12 processors running however it seems like my code cannot access the pool. It prompts me that the paralle pool is idle and will shut down soon.

I think the problem is in the execution of parpool. Any help will be appreciated. Thanks.

It's not quite clear what you're trying to achieve here. You should launch parpool only if your script uses parallel language features like parfor, parfeval, or spmd. If you simply want to run your script in the background, you can use batch.
