TY - JOUR T1 - A note on the capacitance matrix algorithm, substructuring, and mixed or neumann boundary conditions JF - Applied Numerical Mathematics Y1 - 1987 A1 - O'Leary, Dianne P. AB - We develop in this work variants of the capacitance matrix algorithm which can be used to solve discretizations of elliptic partial differential equations when either the original system of equations or one which arises from substructuring has a rank-deficient matrix.
