How to add zero in even position of a matrix

hello,

Suppose I have a matrix

N=5; %can be anything

a=randi([1 4],N,1);

So I am getting a result like a=[1 2 3 2 4]'.

Now I want to add zeros in the even position, so my desired output will be b=[1 0 2 0 3 0 2 0 4 0]'

How I can implement this in the matlab?

Thanks in advance.

Like this

a = [1;2;3;4];
z = zeros(size(a));
b = [a';z'];
b = b(:)
