Error using parpool (line 104)

Failed to start a parallel pool. (For information in addition to the causing error, validate the

profile 'local' in the Cluster Profile Manager.)

Error in parallel.internal.ui.PoolHelper.startPool (line 11)

parpool();

Caused by:

Looks like the permissions in that directory are not correct or have been corrupted.

The easiest thing to try is exiting MATLAB, then rename/delete the "local_cluster_jobs" folder, then restart MATLAB.
