Parallel processing toobox not working on Ubuntu 18.04

5 views (last 30 days)
I have installed Matlab R2018a on a fresh install of Ubuntu 18.04. I can't get the parallel processing toolbox to work.
It seems to be correctly installed:
But when I try to open the parallel pool, I get "undefined function or variable":
And if I open the parallel processing "Manage Clusters" box, The dialog gets stuck on "Loading Profiles...":
All other toolboxes are working fine. `Parfor` loops run through in series, as if they were a normal `for` loop.
Any ideas what the problem is?
Thanks

Also, it's possible that the parallel computing toolbox is not installed correctly.
Can you please try to uninstall that toolbox (in Add-Ons->Manage Add-Ons-> Search for Parallel Computing Toolbox), then install that toolbox again (in Add-Ons->Get Add-Ons-> Search for Parallel Computing Toolbox)?
