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 。
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.
