| Abstract: | Schubert’s method for solving systems of sparse equations has achieved a great deal of computational success. In this paper, Schubert’s method was extended to multiple version, and the compact representation of multple Schubert’s updating matrix was derived. The compact representation could be used to efficiently implement limited memory methods for large problems. |
