Any feedback would be appreciated :-)
A, B are non-singular, and I+AB is invertible.
Thoughts on the equivalent case, i.e., the inverse of (A+B) where A is diagonal and B symmetric matrix, are also helpful.
Hi Changting Xu,
I found this: (I + AB)^-1 = A*(I + BA)^1*A^-1
Best,
Thank you, Anton Vrdoljak! I have tried this identity but ended up with the inverse of (I+BA), which is equivalently challenging problem.

Thank you, it is possible to use Neumann series, but the results are cumbersome. So an explicit inverse is preferable. Nils Wagner
