Abstract :
The author presents a new method for building the inverse of a network matrix based on linear graph representation of the network topology. The sparse tableau approach to network equation formulation is used and the matrix inverses can be in the factorized LU form. When the inverse of a network matrix is already available, this method is efficient for finding the new inverse when the network is modified, e.g. a new network element is added or an element value is altered
