Insert zeros into matrix in matlab

I am trying to insert zeros into a matrix, an example is as follows:

[1;2]

to

[1;0;0;0;0;2]

Can anyone please show me how to perform this in matlab?

[Hikaru]

Can you be more specific? Do you have any conditions that need to be fulfilled to insert the zeroes?
