Generating a random matrix with range

Hi,

I am trying to generate 12*2 matrix. The first column should contain random values between [0 5] and the second column should have random values between [5 20]. Can you help me out with this.

May be something crude like this?

x = rand(12,2);
x(:,1) = 5*x(:,1);
x(:,2) = 5+15*x(:,2)

rand generates uniformly distributed random number in the interval (0,1).

Look at the documentation for more , use randi for integers only etc., rand

Thank you very much. Appreciate your help. It works. I made it a little complicated

a = [0:5]; b = [5:20];

for x=1:12

    m = zeros(1:2);

    V = repmat([(5.*rand(a)); (5+(20-5).*rand(b))],6);

end

disp(V)

Thank you.

That's why I was not able to figure it out. Anyways thank you.
