How do I fill the centers and calculate the distance between two centerpoints in matalb?

Code for two randomly generated circles

figure;
x = rand(1,1); 
y = rand(1,1);
r = rand(1,1);
th = 0:pi/100:2*pi;
a = r*cos(th)+x;
b = r*sin(th)+y;
plot(a,b);
hold on 
x = rand(1,1); 
y = rand(1,1);
r = rand(1,1);
th = 0:pi/100:2*pi;
a = r*cos(th)+x;
b = r*sin(th)+y;
plot(a,b);
hold off

r = rand(1,1);
th = 0:pi/100:2*pi;
a = r*cos(th)+x;
b = r*sin(th)+y;
plot(a,b);

hold on 
x2 = rand(1,1);
y2 = rand(1,1);
r = rand(1,1);
th = 0:pi/100:2*pi;
a = r*cos(th)+x2;
b = r*sin(th)+y2;
plot(a,b);

scatter(x,y,'filled')
scatter(x2,y2,'filled')

hold off 

distance = sqrt((y2-y)^2+(x2-x)^2)

distance = 0.6040

Thank you so much!

It looks like you randomly generated the center points of the two circles. So, I labeled the coordinates of the second circle as x2 and y2. I used pythagorean theorem to find the distance between the centerpoints. Or did you want the distance from the outside of the circle? If that is the case, what if they overlap?

Hi,

I only wanted the distance between the centerpoints, so this is perfect. Thank you!
