Create a plot with a function in a loop?

Hi,

here is my code:

    E = zeros(1,10);
Ith = 100
for k = 1:1:10
  N=2^k ;
  I = 0;

    for i=1:1:N    
      I = I + h*f(((xmin+i*h)+(xmin+(i-1)*h))/2);    
    end

    E(k) = (I - Ith)/Ith;
    plot (k, E(k))
end

I don't find out how create a plot with E(k) in terms of k, for k=1 to 10 in just one plot, so 10 points as the result. Thanks

you have to use the hold on command such that you are adding with plot to the current figure without overwriting your previous plots

figure
hold on

Right, thank you very much!
