Hello all, Suppose I have a set of vectors where
My query is how can we select any vector from set 𝒥and form a matrix of dimension 5 by 500, where 5 corresponds to dimesion of such that n is from 1 to 8 and 500 corresponds to 500 's.
Any help in this regard will be highly appreciated.

Your x[n] have the dimension 5. You have 8 of them. Therefore I'm confused by your 8 and 500.
What is the purpose to select "any vector"? Do you ask for the vertcat command?
If the x[n] are binary vectors, 500 of them with 8 elements cannot be unique: 2^8=256.

x=[1 1 1 1 0 0 0 0;1 0 0 0 1 1 1 0;0 1 0 0 1 0 0 1;0 0 1 0 0 1 0 1;0 0 0 1 0 0 1 0];
r=randi(8,1,500);
y=x(:,r)
