Do changes in .m file after batch submission, while the job is queued, take effect for the current run?

Hi! I have a case submitted to parallel computation using the batch function. However, it has not started yet, and it is queued in the cluster I use. I have realized that I need to do some modifications in the .m file that I have submitted using batch. Then, I would like to know whether the changes that I do in the .m file whose job is queued take effect when the computation starts. Or does Matlab create a copy of the .m file in the moment you use batch in such a way that the changes that you do in the .m file would you only take effect for a new job submission?

Thank you in advance!

The latter. MATLAB attaches all the files it needs with the job. You'll want to delete the job, eg.

c = parcluster;
j = c.batch();
...
j.delete

And then resubmit a new job.
