Detailed Description

This represents matrix consisting of the sum of smaller inversed matrices.

The direct representation in memory is not possible but using in matrix-vector multiplication and some other operations is. The formula is $ \sum^n{A_i^{-1}} $ where $ A_i = R_i A $ and n is the number of aggregates.
