The workers that run the tasks of a communicating job are MATLAB® sessions without displays. As a result, these workers cannot display graphical tools and so you cannot do things like plotting from within pmode. The general approach to accomplish something graphical is to transfer the data into the workspace of the MATLAB client using
pmode lab2client var labindex
Then use the graphical tool on the MATLAB client.
Because the workers running a pmode job do not have displays,
you cannot use Simulink® software to edit diagrams or to perform
interactive simulation from within pmode. If you type simulink at
the pmode prompt, the Simulink Library Browser opens in the background
on the workers and is not visible.
You can use the sim command
to perform noninteractive simulations in parallel. If you edit your
model in the MATLAB client outside of pmode, you must save the
model before accessing it in the workers via pmode; also, if the workers
had accessed the model previously, they must close and open the model
again to see the latest saved changes.
