Answer 1

To programmatically change the value of NumWorkers from 2 to 4 of the local cluster profile, you can use:

myCluster = parcluster('local');
myCluster.NumWorkers = 4;  % 'Modified' property now TRUE
saveProfile(myCluster);    % 'local' profile now updated,
                           % 'Modified' property now FALSE
