Is there any way that you can stop parpool displaying messages upon set up and deletion?
i.e.
>> parpool(2);
Starting parallel pool (parpool) using the 'local' profile ... connected to 2 workers.
>> delete(gcp('nocreate'));
Parallel pool using the 'local' profile is shutting down.
I want to stop these updates displaying.
Thanks for your time.

The only way I've found to do this is to execute the command with evalc. For example:
evalc('parpool(2)');
This should supress the output, but it doesn't give the script parser any insight into the code if you're running this in a script or function. For example, take the code:
function y = square(x) y = x^2;
will not raise any flags with the parser if run normally, but if you execute y = x^2 with an evalc call, then the parser will flag the function call and say that it appears the variables y and x are not used. It shouldn't make it not run, it will just provide an annoying warning that you either have to live with or suppress.
