Riemannian Newton-CG Methods for Constructing a Positive Doubly Stochastic Matrix From Spectral Data
Yang Wang, Zhi Zhao, Zheng-Jian Bai
In this paper, we consider the inverse eigenvalue problem for the positive doubly stochastic matrices, which aims to construct a positive doubly stochastic matrix from the prescrib…
