摘要：
In this study, a new method with algorithms for computing bounds to real eigenvalues of real-interval matrices is developed. The algorithms are based on the properties of continuous functions. The method can provide the tightest eigenvalue bounds and improve some former research results. Numerical examples illustrate the applicability and effectiveness of the new method.
