Note on the Initial Vector Selection in the Subspace Iteration Method

摘要: 本文叙述了三种形成子空间迭代法初始向量组的方法,选用不同的初始向量组作了算例,对于不同的结构可选取不同的初始向量,以便加速迭代收敛的速度。

Abstract: In this paper three methods for forming the initial vectors of subspace iteration are presented and numerical examples with application of each are also given. Different initial vectors should be so chosen for different structures that to make the iteration loop leading to fast convergence.
