计算重根特征向量导数的消元法

Reduced Variable Methods for Calculating EigenvectorDerivatives with Repeated Eigenvalues

本文提出了重根特征向量导数计算的消无法，它分为若干直接算法和一种迭代算法。这种方法概念简单、实施容易、精度良好。该方法可经简单移值用于非重根情况。

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.
