sample (with replacement) random integers all range included

hello,

I want to create a vector X of n uniformly random integers from a range [0 m] without missing any of the numbers between 0 and m.

for example:

n=10 m=3

I want X to contain 10 integers with values 0, 1, 2, 3 and I want all of them to appear at least one time.

i.e. the following vector is not allowed: [3 3 0 1 1 0 3 1 1 0] because it doesn't contain the number "2" at least one time

Is there a matlab function doing that? or I have to create one?

Thanks.

out = randi([0,m],n,1);

t = 0:m;
N = histcounts(out,[t,m]);
l0 = N==0;
if any(l0)
    [~,ii] = max(N);
    jj = find(out == t(ii));
    out(jj(1:nnz(l0))) = t(l0);
end
