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

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);

Change your freq and gain variables, so they're both a function of k. All values will be stored that way and your plot should work. The syntax is:
freq(K) = (K*9000);
gain(K) = (citatel/menovatel);
