Hello everyone.
I have a dataset with 1000 numbers (it is a 1:1000 matrix), I want to get n sample sets of this dataset, each containing m numbers without repetition (m is same for each sample set).
How can I do that?
Thanks in advance.

solution:
v1=[1:1000];%put your dataset here
n=16;
m=4;
[~, ind] = sort(rand(n,length(v1)),2);
samples=v1(ind(:,1:m))
