I want to draw a beam, but I refer to the example in this article.
Code source
I want to draw the beam as shown below
figure('NumberTitle','off','Name','Figure 11.9 in Polar','Position',[0 0 600 850]);
subplot(2,1,1);
polardb(angle*pi/180,10*log10(abs(C1).^2),-60,'b');
title('Beampattern Using Definition');
grid on;
Will show the following error
Where is polardb defined?
How to correct it?
Thx.
