| Abstract: | Reduced variable methods for calculation of eigenvector derivatives with repeated eigenvalues aredeveloped in this paper. The present method has two formats: some direct algorithms and an iterativealgorithm. These procedures possess following merits: simpler concept , easy implement and good pre-cision. The methods are used easily to calculate the eigenvector derivatives with non-repeated eisenval-ues. |

| Keywords: | eigenvector derivative eigenproblem with repeated eigenvalue sensitivity analysis reduced variablemethod. |
