abdalrhman - if you want to exit out of your loop once the tolerance is less than zero, then put in a condition to do so

    for EJ=EJ+.015:.01:E1-.01
        Q1=sqrt((E1-EJ)/R1);
        Q2=sqrt(abs((E2-EJ))/R2);
        Q3=sqrt((EJ-E3)/R3);
        tol=Q1-Q2-Q3l
        EJ;
        if tol < 0
            break;  % exit loop since tolerance is now negative
        end
        tolnew=tol;    
    end
