Therefore, MATLAB does mX_check<=0.1 to be true at the same time in order to break out of the loop, plus you want to break out regardless of those values if Nx ever gets more than 5000, you need to do it this way: (resolution_check < 8 || mX_check > 0.1) && Nx<5000, Now it will break if Nx ever meets or exceeds 5000, regardless of the values of resolution_check < 8 and mX_check. Otherwise, the expression is false.
