我们报告的隐式重新启动Lanczos算法的ARPACK和Jacobi-Davidson算法求解大型稀疏广义对称矩阵特征值问题的比较。这些问题发生在空腔谐振器中电磁驻波的最低频率的计算中。计算域采用基于棱边单元的有限元法离散，避免了伪模态。
We report on a comparison of the implicitly restarted Lanczos algorithm as implemented in ARPACK and the Jacobi-Davidson algorithm for solving large sparse generalized symmetric matrix eigenvalue problems. These problems occur in the computation of a few of the lowest frequencies of standing electro-magnetic waves in cavity resonators. The computational domain is discretized by a finite element method based on edge elements to avoid spurious modes.
