Unable to see Graph

Hi,

Following is the code of sinc function which I am trying to plot. However, I do not see anything. Any help will be appreciated.

h=5;
lambda=h;
beta=2*pi/lambda;

for theta=0:0.01:2*pi
    T=abs(sinc(beta*h*cos(theta)));
% T=sin(beta*h*cos(theta))/(beta*h*cos(theta));
polarplot(theta,T);
hold on;
end

Instead of using a for loop, take advantage of matlab's ability to work with vectors (don't forget the element-wise period for T2):

 h=5; lambda=h; beta=2*pi/lambda;
 theta=0:0.01:2*pi;
 T1=abs(sinc(beta.*h.*cos(theta)));
 T2=sin(beta.*h.*cos(theta))./(beta.*h.*cos(theta));
 polarplot(theta,T1);
 hold on;
 polarplot(theta,T2);

Thank you sir!
