Running two loop together at the same time

Hey everyone !

I am currently trying to run the two while loops at the exact same time. When the user click on a button I would like somethings like this to happen :

function start_Callback(hObject, eventdata, handles)

while

xxxx

end

while

xxxxxx

end

I would like this two while loop to run together (I hope it's understandable ^^' ). I dind't find the solution to my problem on the forum, so sorry if it has already been asked ....

Thanks you very much for your anwser !

Try using parfeval, such as the following pseudo code

function start_Callback(hObject, eventdata, handles)
pool = gcp('nocreate');
if isempty(pool)
    % Explictily start a 2-worker pool
    pool = parpool('local',2);
end
f1 = pool.parfeval(@while1,...);
f2 = pool.parfeval(@while2,...);

A couple of notes

1. You might want to start a pool elsewhere or with a different size.
2. You'll need to refactor your while-loops as "units of work". That is, write them as subfunctions that can be called on their own. Look at the parfeval doc for additional arguments required (input/output, etc.).
3. After spawning the code, you might need to cancel the tasks.
