Hi. Why i can`t get graphic? what is wrong?

m=0.221;

i=0;

for w=0:0.01:2

i=i+1;

k1=5./(6.*exp(m.*w));

a1=(-37.52.*(w.^3).*(m.^3)+112.56.*m.*(w.^3)+26.77.*(m.^2).*(w.^2)-26.77.*(w.^2)-8.69.*m.*w+1).*k1;

a2=(112.56.*(w.^3).*(m.^2)-37.52.*(w.^3)-53.54.*m.*(w.^2)+8.69.*w).*k1;

Ree=a1.*cos(w)-a2.*sin(w);

Imm=a2.*cos(w)+a1.*sin(w);

C0=w.*((m.^2)+1)*Imm;

C1=m.*Imm-Ree;

if i==10

i=0;

if C0<0

end

end

   plot(C0,C1),grid;

end

Your C0 and C1 are scalars. To see the point you can do this:

scatter(C0, C1)
grid;

it`s worked. thank you

If it worked you should accept the answer so it can help others too!
