Hi everyone,

I practice parfor code in help(matlab). i run code but dont know how to show variable in parfor.

   parfor i = 1:4
    temp = struct();
    temp.myfield1 = rand();
    temp.myfield2 = i;
end
parfor i = 1:4
    temp = struct('myfield1',rand(),'myfield2',i);
end

Thank for helping me.

Just display them.

For example,

parfor K = 1 : 20; t = getCurrentTask(); fprintf('task %d got iteration %d\n', t.ID, K); end

output

task 1 got iteration 1
task 2 got iteration 2
task 3 got iteration 4
task 3 got iteration 3
task 4 got iteration 7
task 1 got iteration 10
task 1 got iteration 9
task 1 got iteration 8
task 2 got iteration 13
task 2 got iteration 12
task 2 got iteration 11
task 4 got iteration 6
task 4 got iteration 5
task 1 got iteration 18
task 3 got iteration 15
task 3 got iteration 14
task 2 got iteration 19
task 3 got iteration 20
task 4 got iteration 17
task 4 got iteration 16
