GLOBAL data is never shared between your desktop MATLAB session and the workers running jobs and tasks. However, you might find it somewhat easier to open a MATLABPOOL and then use PARFOR to get your job done. Perhaps something a bit like this:
matlabpool open local 3
done = false;
myFcns = {@myFcn1, @myFcn2, @myFcn3};
overallState = 0;
while ~done
parfor ii = 1:3
result(ii) = feval(myFcns{ii});
end
overallState = overallState + sum(result);
done = (overallState > 42);
end
In other words, you could put your three functions into a cell array of function handles. The PARFOR loop runs these in parallel, and collects the results into 'result', and you can operate on that in your MATLAB session, and then do some more stuff in parallel.
