| Abstract: | This paper establishes an improvement on the QL algorithm for a symmetric tridiagonal matrix T so that we can work out the eigenvalues of T faster. Meanwhile, the new algorithm don't worsen the stability and precision of the former algorithm. |
| Keywords: | Eigenvalue problem symmetric tridiagonal matrix QL algorithm |
