Displaying random numbers as a graph

11 views (last 30 days)
I am generating random numbers with the rejection sampling, like in this picture. How can I see my generated random numbers as points, like in this picture?

One approach is to use the inpolygon function:
x = linspace(0, 10);
y = exp(-(x-5).^2)*0.2;
r = rand(1000,2).*[10 0.25];
[in,on] = inpolygon(r(:,1),r(:,2), x, y);
hold on
plot(r(:,1), r(:,2),'.r')
plot(r(in,1), r(in,2), '.g')
hold off
Experiment with it to get the result you want.
