Can worker be removed from Matlab Distributed Computing Server without error?

I'm using MATLAB 8.6 (2015b), Parallel Computin Toolbox 6.7 (2015b) and MATLAB Distributes Computing Server 6.7 (2015b).
My cluster is made out of several laptops that double as regular work stations of my research group.
My code has a parfor-loop that should preferably work similarly wether the client runs it locally or in the cluster.
The problem is that every once in a while, one of the worker laptops crashes or somebody has to disconnect his/her laptop and this causes the parfor-loop in the client machine to throw an error.
Is there some way to detect if a worker has left the pool and recalculate the corresponding loops in the rest of the pool?

parfor is the wrong instrument for this. See parfeval or perhaps batch, as those permit the client to check the status of workers and potentially start new tasks to account for failures.
