I want to generate the random circle with fix radius within a specific area like 0<x<1 0<Y<1 and each generated circle must be checked with all previously generated circle to make sure there is no interference

the progream will be finished when there is no more room for new circle is any functions there can do this?

x<1, y<1 is an infinite area. So the code will never stop. Do you mean -1<x<1, -1<y<1?

Apologies for the confusion. I mean the area like 0<x<1 0<Y<1

在 MATLAB Online 中打开

r = 0.1 ;   % radius of circle 
x = 0:2*r:1 ; 
y = 0:2*r:1 ; 
[X,Y] = meshgrid(x,y) ;
th = linspace(0,2*pi) ; 
xc = r*cos(th) ; yc = r*sin(th) ; 
figure
hold on
for i = 1:length(x)
    for j = 1:length(y)
        plot(X(i,j)+xc,Y(i,j)+yc) ; 
    end
end
