In Matlab's Parallel Computing Toolbox, how can I choose which lines of code I send to each worker/core?

I am running a for loop where I compute 3 variables separately and then add them all up in the end, i.e.

for time=0:endtime
   calculate_a(a,u);
   calculate_b(b,u);
   calculate_c(c,u);
   u=a+b+c;
 end

I would like to parallelise this loop so that each calculation of a, b and c is done by an individual worker and they are all put together for u calculation, i.e.:

   for time=0:endtime
     calculate_a(a,u); % performed by worker 1
     calculate_b(b,u); % performed by worker 2
     calculate_c(c,u); % performed by worker 3
     % all workers share their outcome and perform
     u=a+b+c;
   end

I am new to parallel computing in Matlab. Can you help me figure out how to go about this? Also, are there any problems in creating a stand-alone program (.exe) from Matlab when using parallel computing?

Many thanks!

Use createJob, createTask, submit, and fetchOutputs. The documentation is pretty clear but let me know if you need more help.
