How do you duplicate an entire vector? For example:
A=[1 2 3 4];
How do I get the following?
1 2 3 4 1 2 3 4 1 2 3 4
I thought repelem(A,3) would do the trick, but that replicates each element at a time.

You almost got it. Try
repmat(A,[1 3])

Ran in:
A=[1 2 3 4];
repmat(A,1,3)
ans = 1×12
1 2 3 4 1 2 3 4 1 2 3 4
