How can I access to variables after a parallel pool?

Hi,

It's my first time to use the parallel toolbox in matlab, and I have a question about variables here.

My part code is as follows:

c = parcluster('local');
job = createJob(c);
createTask(job, @computeT, 1, {{sub(1),sub(2),sub(3),sub(4),w1,alp1,bet1,Carray,x} ...
    {sub(1),sub(2),sub(3),sub(4),w2,alp2,bet2,Carray,x} {sub(1),sub(2),sub(3),sub(4),...
    w3,alp3,bet3,Carray,x} {sub(1),sub(2),sub(3),sub(4),w4,alp4,bet4,Carray,x}});
submit(job);
wait(job);
ks = fetchOutputs(job);
delete(job);   %line 9
delete(gcp);
clear job;
kp = sum(cell2mat(ks));
rp = 0.5*pi*pi*kp;
tp = x(1)*x(2)*x(3)/(4*pi)*rp;

There are 4 workers on local cluster. After the parallel job, I try to end the pool (lines9,10,11). But I failed, as I cannot find variables kp, rp, tp from my current workspace. How can I access those variables after the parallel pool, please?

Thanks.
