WebPartitioned Matrices). 1. To transpose a partitioned matrix, treat the sub-matrices in the partition as though they were elements of a matrix, but transpose each sub-matrix. The transpose of a p×q partitioned form will be a qp× partitioned form. 2. To multiply partitioned matrices, treat the sub-matrices as though they were elements of a matrix.

Now define z = x1 + Ax2 where A = − Σ12Σ − 122. Now we can write. cov(z, x2) = cov(x1, x2) + cov(Ax2, x2) = Σ12 + Avar(x2) = Σ12 − Σ12Σ − 122 Σ22 = 0.

WebI'm not sure if the OP was looking for a proof or derivation. In my mind a derivation is bit different than what Royi provided. I have looked for but never seen a derivation of the various versions of the Matrix Inversion lemma. Usually, the proof is left as an exercise for the reader.
