Problems using parfor loop

% It would have been very helpful for if get some probable solution for the
% following problem I am facing. Thanks in Advance.



%% Problem 1 : Error => Idx is not available after parfor loop ( As a result, TT showing me undefined )

AA = [4 5 6];
parfor r = 1:5
        [Idx]= max(AA);
end
TT = Idx;

%% Problem 2: Error => parfor loop cannot run due to the way variable "coords" used.
parfor r = 1:5
       coords(r,:) = "Some Arbitary Function" % I can not share the real code here
end

For the first problem, write this

AA = [4 5 6];
parfor r = 1:5
    Idx(r)= max(AA);
end
TT = Idx;

Regarding the second one, it might be due to the nature of the output of the function you cannot share.
