MATLAB: How to plot curve using data from for loop

plot using for loop

i need help with plotting this equation using for loop. I found solution already posted here, but i wasnt able to implement it on my problem. (Currently this will plot only one dot (i assume thats the last value from for loop)
for K = [1 2 3 4 5]
    Q=0.49;
    Rac=0.0015;
    m=K;
    freq=(K*9000);
    Cr=1/(2*pi*Q*freq*Rac);
    Lr=1/(((2*pi*freq)^2)*Cr);
    Lp=m*Lr;
    w=2*pi*freq;
    w0=1/(sqrt(Lr*Cr));
    wp=1/(sqrt(Lp*Cr));
    Race=14685.973;
    Qe=(sqrt(Lr/Cr))*(1/Race);
    %///////////////////////////////////////
    citatel=((w^2)/(w0^2).*(sqrt(m.*(m-1))));
    menovatel=(((w^2)/((wp^2))-1)+1i.*(w/w0).*(((w^2)/(w0^2))-1).*(m-1).*Qe);
    gain=(citatel/menovatel);
    plot(freq,gain);
end

Best Answer

Either insert hold('on') bevor the loop, such that the plot() command does not delete formerly existing points. Or collect the data at first and draw them after the loop as a line:
freqV = zeros(1, 5);
gainV = zeros(1, 5);
for K = 1:5
  ...  % No changes here
    % Instead of:
    % plot(freq,gain);
    freqV(K) = freq;
    gainV(K) = gain;
  end
  plot(freqV, gainV);
