dc.description.abstract在這篇論文中,我們學習二次特徵值問題 ( A + B + C)x = 0 的數值解,其中A、B、C是n維的實矩陣且A是可逆矩陣。首先將二次特徵值問題轉換成較大的標準的特徵值問題 其中 是一個維度2n的矩陣。然後應用Householder轉換與QR迭代法去取得 矩陣的特徵值。為了在迭代的過程中能更快地得到特徵值,我們提供一個對QR迭代法的平行方法。這個對QR迭代法的平行方法在資料傳輸方面我們減少了約三分之二的資料傳輸時間。zh_TW
dc.description.abstractIn this paper, we study the numerical solution of the quadratic eigenvalue problem ( A + B + C)x = 0, where A, B, and C are real nxn matrices, and A is nonsingular. We transform the quadratic eigenvalue problem into an enlarged standard eigenvalue problem where is a matrix of order 2n. Then we apply the Householder method and the double-shift QR iteration to get the eigenvalues of matrix . In order to obtain the eigenvalues faster, we propose a parallel method for the double-shift QR iteration. Our parallel method for the double-shift QR iteration decreases data-transferring time to one-third.en_US
