I have arrays of two columns, I want to plot multiple circles where the center of each cirlce is determined in each row, as each row consists of two numbers. Thank You

在 MATLAB Online 中打开

C = rand(10,2) ;
plot(C(:,1),C(:,2),'o','Markersize',10)

If you want circle with given radius R.

C = rand(10,2) ;
R = 4 ; 
th = linspace(0,2*pi) ;
x = R*cos(th) ;
y = R*sin(th) ; 
figure
hold on
for i = 1:10
    xc = C(i,1)+x ; 
    yc = C(i,2)+y ; 
    plot(xc,yc)
end
