Applications of Improvable Cholesky Factorization of Symmetry Matrix in Eigenvalue Problems
【摘要】 利用对称矩阵的改进Cholesky分解 ,估计在给定区间 (a ,b)内对称矩阵A特征值的个数 ,进而发展成一种求对称矩阵特征值的近似算法
【Abstract】 By applying the type improvable Cholesky matrix factorization of symmetrical matrix, we estimate the number of eigenvalues of a symmetry matrix A in interval ( a,b ). Thus, and approximate computational method on finding the eigenvalues of a symmetry matrix is developped.
