摘要: 非对称矩阵广义特征值问题的并行计算是大规模工程计算中的基础问题之一。迄今为止,国内外关于该问题的研究进行得很少,提出的有效算法不多。首次将连续同伦算法应用于非对称广义特征值问题的并行求解,提出并行连续同伦算法。

Abstract: Parallel computation for the nonsymmetric generalized eigenvalue problem is one of the fundamental problems in large scale engineering computation.A homotopy continuation algorithm is proposed to deal with parallel computation for this eigenvalue problem.Numerical results show that it has advantages of high parallel efficiency and fast convergence speed.

Key words: parallel computation, homotopy continuation algorithm, nonsymmetric matrix, generalized eigenvalue problem
