MATLAB: How to shift the vector element inside of the vector

Question

Is there any fast way I can shift a vector, for example given:

a = [1 2 3 4 5]

How can I shift of two positions the vector in such a way that I get:

a = [0 0 1 2 3]

Thanks.

Answer 1

Another option:

a = [1 2 3 4 5];
as = zeros(size(a));
as(end-2:end) = a(1:3)
as =
     0     0     1     2     3
