I have 8 cores, 32gb ram. i used parpool in matlab 2017. and it was fine. I increased the number of works from default to 8 to match my cores. and i had no issues.

now i updated to matlab 2018 and every time i try to run code it freezes. anyone knows what im doing wrongly?

please see the screenshots of my settings

Total_Tests =40;
mat_size='10000x10000';
parpool(8)  % parrallel pool
missing=[0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9];
parfor k=1:length(missing)
    for i=1:Total_Tests
        MV=missing(k);
        data(MV,i,mat_size); % function for data creation
    end  
    disp( ['Test: ',int2str(k),' OK!'] );
end
disp(['matrix size ', '( ',mat_size,' )', ' : all ',int2str(Total_Tests), ' data simulations ', ' completed!' ]);
delete(gcp)  % stop parrallel computing
