【Abstract】 In this paper, the two sided Lanczos recursion is used to transform the unsymmetric generalized eigenvalue problem into tridiagonal standard eigenvalue problem. Application of the two sided QR algorithm with origin shift to solve the eigenvalue problem of tridiagonal matrix is presented. Therefore, all solutions are performed in real arithmetic. The real part and complex part of the complex eigenvalue can be extracted separately.更多还原
