Are all of $A,B,C,D,E$ square matrices of the same size? What are $h$ and $k$? Scalars, vectors or square matrices? –  user1551 Dec 6 '12 at 23:24

How about using Schur complement (another reference on the internet)?

@Victor It's already solved in the Wikipedia entry I linked to, isn't it? –  user1551 Dec 6 '12 at 23:03
