Hi, I have some problem with drawCicle. Here is the code.
% draw tier 1 and tier 2 circles
drawCircle(baseStation.x, baseStation.y, tier1Radius, 100, 'r--');
drawCircle(baseStation.x, baseStation.y, tier2Radius, 100, 'b--');
And the error is:
*Undefined function or variable 'drawCircle'.*
Can someone help me out?

drawCircle is not a MATLAB function. It appears to be an Octave function.
Also, there is an implementation of a drawCircle function at https://www.mathworks.com/matlabcentral/answers/20077-counting-plots-on-a-figure

Ya, i get it. Thanks sir. ^_^
theta = linspace(0,360);
y=radius*sind(theta)+center(2);
x=radius*cosd(theta)+center(1);
plot(x,y,color);
axis([xmin,xmax,ymin,ymax])
end
