canceled is placed in the task object's ErrorMessage property,
and the worker session running the task is restarted.

j, that is pending, queued, or running. The job’s
State property is set to finished, and a
cancel is executed on all tasks in the job that are not in the
finished state. A job object that has been canceled cannot be
started again.
If the job is running from a MATLAB® Job Scheduler, any worker sessions that are evaluating tasks belonging to the job object are restarted.
If the specified job or task is already in the finished state,
no action is taken.
