Is there an easy way to restructure a 3x3 matrix to become a 9x9 matrix, with the original values on the diagonal and all other cells are left with a value of 0.

i.e. cell 0 0 value stays in 0 0, 1 0 moves to 1 1, 2 0 moves to 2 2, 1 0 moves to 3 3, 1 1 to 4 4 etc, up to 3 3 value is in 9 9, [if i have my cell referencing correct that is!!]
