Periodically save matrixes (or workspace) within PARFOR loop

I have been using a parallel loop (Parfor) in Matlab, and here is part of my code. (It is supposed to run a few days so I want to save outputs periodically.

parfor i = 1:N
                     
     ...

     out1(i,:) = result1;
           
     out2(i,:) = result2;

       
    if mod(i,100) == 0      
        % Here, I want to save out1 and out2 (export with .mat file) 
    end     
  
  
end

How can I save out1 and out2 for every 100th iteration? (Saving workspace for every 100th iteration is also okay)

Note that the order which the files are saved in is not guaranteed: the parfor iterations are not necessarily performed in the order i = 1:N, which also means that your code could end up saving files at very unequally distributed times during runtime (worst case: all iterations where mod(i,100)==0 are evaluated first/last).
