显示 更早的评论

coords=zeros(n,2); for i=1:n coords(i,1)=rand*1000 coords(i,2)=rand*1000 end z=coords(:,1); c=coords(:,2); figure(1) plot(z,c,'-*') i need the final figure be like this one

coords=zeros(10,2);
for i=1:10
coords(i,1)=rand*1000
coords(i,2)=rand*1000
end
z=coords(:,1); c=coords(:,2); figure(1)
quiver(z,c)
