How do i randomly distribute 4 numbers in 1*100 matrix?

Hi Helpful minds,

I have 4 numbers, [2, 4, 7, 9] I want to generate a 1*200 Matrix which have only these 4 numbers randomly distributed. I am expecting a matrix like: [7, 9, 4, 4, 2, 9, 7, 4, 2, .....]

Thank you in advance Rony

Hi Rakibul,

What you can do is create a matrix containing the numbers you want. I will call it L. Then create a random integer matrix that goes from 1 to 4. This matrix will then be used to index into L. The matrix M will then have the 4 numbers from L randomly distributed. (See code below)

Matt

 L = [2,4,7,9];

 ind = randi([1 4],1,200);

 M = L(ind)

Thanks So much Matt.

I was wondering if there is a direct function to do such thing. But anyway, your solution is direct enough for me. thanks
