plot equation help

Hello!

I need help with plotting equation in matlab. I need to plot curve using an equation. The curve should look like that one in attached picture (please do not mind description)

so far ive tried this, but it plots only one point. i dont know how to correctly use for cycles. This is my m-file:

Q=0.49;

Rac=0.0015;

freq=20000;

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);


%///////////////////////////////////////

for m=1:0.1:5;
    
    for freq=20000:10:30000;
    
    ((w^2)/(w0^2)*(sqrt(m*(m-1))))/(((w^2)/((wp^2))-1)+1i*(w/w0)*  (((w^2)/(w0^2))-1)*(m-1)*Qe);
    
    end
     
    

   
end

i was trying to plot the curve using command

 plot(freq,m)

in command window

Any help would be much appreciated.
