MATLAB 随机生成互不重叠的多个矩形

建立m文件draw_rectangle.m.

其中p生成矩形的个数

function  draw_rectangle(p)

t = 1;
x = rand(1)*10;
y = rand(1)*10;
w = rand(1)*10;
h = rand(1)*10;
b =[x y w h];
rectangle('Position', b)
a{t} =b;

flag =1;
while flag ==1
    x = rand(1)*10;
    y = rand(1)*10;
    w = rand(1)*10;
    h = rand(1)*10;
    b =[x y w h];
    num = 0;
     for j = 1:t
          if ~rectint(b,a{j})
              num = num +1;
          end
     end
     if num == t
         hold on;
         rectangle('Position', b)
         t = t+1;
         a{t} =b;
     end
     if t == p
         break
     end
end
