How to insert calculation values in to a zero matrix

Dr is the result matrix (4 by 4) and I want to insert only the third non-zero column into a new matrix like Z.

Dr =

0 0 -0.0618 0

0 0 -0.0618 0

0 0 0.9884 0

0 0 0.9884 0

Z = [-0.0618;-0.0618;0.9884;0.9884]

I've been tried a lot of ways but none of them works. Therefore, any advises are very welcome. Thanks!
