摘要
In this paper we describe a new tridiagonal equation solver, based on a rank-one updating strategy an the repeated partitioning of the system matrix into 2 x 2 submatrices. On this basis, a recursive decoupling method is developed [2,3], which operates on the tridiagonal linear system, enabling the solution to be expressed in explicit form and solved independently on a multiprocessor system. We will show, in fact, that the Recursive Decoupling method is intrinsically parallel and can be implemented as an efficient parallel algorithm.
