Hello, I have a matrix Y that's nx2. Say in this case n=5. (n can only take the values 3,5 or 8 but I guess that doesn't matter)
Y =
9 2
10 2
9 3
9 4
10 4
I want to randomly choose on of these rows so I can use them as coordinates!
Many thanks,
Phill

k = randi(size(Y,1)); % the random row index
Y(k,:) is the random row
