i need help for this code

since i plot this code i get a line on the graphe is it normal or i made a mistake on the code?

f=(0:10);
t=(0:0.1);
w=2*pi*f;
rin=0.71;
%y=rin*exp(*-1i*w*t);
y=0.71*exp(-1i*w*t);
%rin=abs(y);
plot(real(f),imag(y));

Hey yann,

You have a problem in this line of your code:

t=(0:0.1);

This just sets t to 0. You must specify the steps in creating the array. Use:

t=(0:0.01:0.1);

You can vary the step size according to your needs. Additionally, use .* operator instead of * to get your code running.
