How get this 'for loop' to plot 100 values in matlab?

Question

How get this 'for loop' to plot 100 values in matlab? Can't figure out where to include the 'i'
This is a monte carlo analysis plot of the operating point of a common-emitter amplifier

for i=1:100
   Rb = 377000 * (1 + (rand()*2-1)*0.01);
   Rc = 1000 * (1 + (rand()*2-1)*0.01);
   Beta = 200 + 100*(rand()*2-1);
   Ib = (12-0.7)/Rb;
   Ic = Beta*Ib;
   Vc = 12-Ic*Rc;
   plot(Vc,Ic*1000,'.');
   end

enter image description here what about this ? add hold on you got than you 100 points ??

 figure;
 axes('NextPlot',add'); %This remove the need to call hold on, also  I added an extra ' for SO formatting
 for i=1:100
    Rb = 377000 * (1 + (rand()*2-1)*0.01);
    Rc = 1000 * (1 + (rand()*2-1)*0.01);
    Beta = 200 + 100*(rand()*2-1);
    Ib = (12-0.7)/Rb;
    Ic = Beta*Ib;
    Vc = 12-Ic*Rc;
    plot(Vc,Ic*1000,'.');
  end

they are supposed to have very similar syntax, ........actually tying in 'hold on' made it work thanks! not sure what that does. i'll investigate! – Andre Marin Feb 23 '13 at 20:56
@slayton why ? what 's the difference ?? – Engine Feb 25 '13 at 09:10

@Engine, its mainly a stylistic difference but it helps educate people about how to create objects exactly how you want them rather than creating them and modifying them in 2 calls – slayton Feb 25 '13 at 13:40
