Help!! I'm trying to plot a function where the output changes with different values of the array. my for loop works, I can see the values changing. I just have trouble with plotting it. I get a graph with nothing in it! any help is appreciated!

gamma=0.268;
dt=0.05;
T=10;
t=0:dt:T



for tt=0:dt:T
    
x=gamma*sqrt(((1-cos(0.7255*t)).^2+(sin(0.7255*t)).^2)/((1-gamma*cos(0.7255*t)).^2+(gamma^2)*(sin(0.7255*t)).^2))
y=abs(x)

end

figure;
hold on;
grid on;



plot(t,y);

title('1b)')
xlabel('frequncy (GHz)')
ylabel('|Gamma|')

hold off;

gamma=0.268;
dt=0.05;
T=10;
t=0:dt:T
for tt=1:length(t)  
x=gamma*sqrt(((1-cos(0.7255*t(tt))).^2+(sin(0.7255*t(tt))).^2)/((1-gamma*cos(0.7255*t(tt))).^2+(gamma^2)*(sin(0.7255*t(tt))).^2))
y(tt)=abs(x);
end
figure;
plot(t,y); grid on;
title('1b)')
xlabel('frequncy (GHz)')
ylabel('|Gamma|')

More: No Loop is required here, try

gamma=0.268;
dt=0.05;
T=10;
t=0:dt:T;
x=gamma*sqrt((1-cos(0.7255*t).^2+(sin(0.7255*t)).^2)./((1-gamma*cos(0.7255*t)).^2+(gamma^2)*(sin(0.7255*t)).^2));
y=abs(x);
figure;
plot(t,y); grid on;
title('1b)')
xlabel('frequncy (GHz)')
ylabel('|Gamma|')

yes you are right, I forgot the ./ and it worked. thank you very much!
