Partitioned matrix operations

Hello, Here's a Mathematica newbie question. Say I have a matrix, M, defined as, M = {{A, B}, {C, 0}} where A is nxn, B is nxm, C is mxn, and the zero sum matrix is mxm. I would like to perform an operation on the matrix M without fully defining A, B, and C and get a result in terms of A, B, and C. For example, if I wanted to determine the matrix inverse of M in terms of A, B, and C. Is this possible in Mathematica? I've unfortunately not found anything in the docs that indicates that this is possible. Thx.
