Duplicating an entire vector

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.

Answer 1

[Chad Greene]

You almost got it. Try

repmat(A,[1 3])

Answer 2

[Davide Masiello]

A=[1 2 3 4];
repmat(A,1,3)

ans = 1×12

1 2 3 4 1 2 3 4 1 2 3 4
