I have a Matlab script that needs two functions in the same folder. I can run it on my own computer under the same folder, but I don't know how this works in the parallel batch job. Say script name: script.m Two functions: function1.m function2.m

Yes, it works in cluster, too.

By default, 'AutoAttachFiles' of batch function is true, so if your script.m requires external custom functions, batch will analyze file dependencies and send these files to the cluster automatically.

If this does not work, you can forcibly add files by using AttachedFiles property. The following command is an example of running script.m using 4 workers in parallel. (1 worker as a batch handler and 3 workers in parallel pool).

job1 = batch('script', 'AttachedFiles',{'function1.m','function2.m'}, 'Pool', 3);
