Hello ! I need quick help. i have created a bunch of hexagons within an area. all hexagons have same radii but i want to make a bunch with different radii of each hexagon. the attached figure here is a way i created my plot.
this way i have done
j = 0;
i = 1;
Centre_x(i) = 100;
Centre_y(i) = 100;
Radius = 250;
R=1000; % radius of macrocell in meters
v_x = 100+R * cos((0:6)*pi/3); %Vertexes
v_y = 100+R * sin((0:6)*pi/3);
v_x_b = v_x;
v_y_b = v_y;
while Centre_x(i) < R+100
while Centre_y(i) < ((((3)^0.5)*R)/2)+100
i = i + 1;
Centre_x(i) = Centre_x(i-1);
Centre_y(i) = Centre_y(i-1) + (((3)^0.5)*Radius);
end
j = j + 1;
if mod(j,2) == 0
i = i + 1;
Centre_x(i) = Centre_x(i-1) + 3*Radius/2;
Centre_y(i) = 100;
else
i = i + 1;
Centre_x(i) = Centre_x(i-1) + 3*Radius/2;
Centre_y(i) = ((((3)^0.5)*Radius)/2)+100;
end
end
for i = 1 : length(Centre_x)
Tempx(i,1) = Centre_x(i)- Radius;
Tempx(i,2) = Centre_x(i) - Radius/2;
Tempx(i,3) = Centre_x(i) + Radius/2;

Can't you just make R and/or Radius a random number within some range?
