How would I randomly pick one point from N points in MATLAB?

Question

I use this code to create and plot N points:

N = input(\'No. of Nodes:\');
data = rand(N,2); % Randomly generated n no. of nodes
x = data(:,1);
         


        

Answer 1

Just take the first one. Being a product of the rand()-function, it should be random enough for anybody :-)

plot(x(1),y(1),'o');
